I like to at least think it was a software company like Microsoft who wrote the part about devices being required to report their max-power in milliamps. *forehead slap*

http://www.beyondlogic.org/usbnutshell/usb5.htm#ConfigurationDescriptors

bMaxPower. 1 byte. Current in 2mA units. The idea is they can code from 0ma to 510ma in 2mA steps using one byte.

It would have been nice to have specified a max current of 1A and used 4ma units so USB 2.5 inch hard disks could spin up powered by one USB connector. Which they can do with Firewire.

I must say the fact that bMaxPower is in the wrong units never occured to me - I just converted the 5W figure in the Samsung data sheet to mA by dividing by 5. Actually, measuring spin up power as opposed to current seems a bit unhelpful - since it's a spike it seems more natural to talke about peak current rather than peak power.

Wrong.

for instance, Guttman claims you can't play HD DRM'd content on a DVI port as fact. That is complete and utter rubbish, as seen on this example http://www.samsung.com/au/products/monitors/tft/tvmonitor/275t.asp?page=Features - where it clearly states HDM is playable through a DVI connector.

That's just one example. This ZDNet guy has actually tried out HD content on Vista and is objecting because of actual real experience to the contrary of what this Guttman guy only 'theorises'.

A bug with audio + network speeds (which, btw, Microsoft has admitted is a bug they're working on fixing) has nothing to do with spreading FUD as fact about Vista DRM tech.

Pros:

• More reliable: No moving parts; no head crash; no wobble
• Low latency, high throughput (all seem to offer low latency, some don't do so good on throughput)
• Low power requirements
• Low heat production
• No noise

Cons:

• High price
• Small capacity

It's not blamed on MS and in fact, I haven't seen the name of the company quoted in comments before yours. This is not so frequent ... This time, we have real reasons to believe that this package has been created by Windows users. Just take a look to the installation page on their website: the Winzip icon in front of the .tar.gz link, the section name within square brackets, the ./autorun program that should be run by the user, and so on ...

Some passages are delicious:

The "Administrator Login" window. Fun. They also want to open a graphical root session, then download the file from here. However, the user still have to understand by himself that he has to open a console, go into the right directory and type the command written after the # .

You do not specify in which country you live. In the Netherlands, you can buy a wide range of DVR's for amounts between EUR 150 (crappy no-name brands) and EUR 500 (with HD support, 2 tuners, big harddisk, etc.).

For example Samsung has quite a few, but I don't know whether they sell them only in Europe (PAL) or in other places as well. There's several other brands that sell 'em too, e.g. Sony.

Pay attention to such things as: does it support an electronic program guide (and will this work with your cable provider), is it actually easy to capture e.g. all airings of particular shows/series, is it easy to navigate the menus or is programming it such a nightmare that you probably won't ever use it after the first week.

• Pure plug and play, automatically popping up in rhythmbox.
• Plays ogg files. (And because ogg has a better compression than mp3 at the same bit rate, you either get better quality or more music on your 4GB.)
• Long battery life.

I heard recently about some of the Samsung Yepp players supporting Ogg Vorbis as well. A quick search turned out at least a couple of models that list support for it:

(slightly confusingly, not all Samsung websites do mention Ogg support for these same models)

I believe the current figure is something more like a hundred thousand writes per memory cell; with a load-distributing file system, this means the lifetime is about the amount of time taken to write the whole device 100k times, which (since flash writes are fairly slow; a few megabytes per second at best) is up there with hard-drive lifetimes.

Flash can easily be made to have ECC and bad-sector remapping ... if you look at the spec sheet http://www.samsung.com/Products/Semiconductor/NAND Flash/SLC_LargeBlock/16Gbit/K9WAG08U1A/ds_k9xxg08u xa_rev11.pdf (linked to from an HTML summary at http://www.samsung.com/products/semiconductor/NAND Flash/SLC_LargeBlock/16Gbit/K9WAG08U1A/K9WAG08U1A. htm ) for a Samsung flash chip which is probably the one in these drives, you'll observe that it has 256Mbits of spare capacity for that sort of purpose. Doing reads and writes in units of a whole sector means you can use quite efficient error-correcting codes.

Well, I just went through that exercise after researching for a few months. My goals (in order) were 100% free drivers, a significant decrease in noise and heat from my previous system, and small size. As a side benefit, I ended up completely legacy-free. Here's what I ended up with:

• Intel DG965PZ
• Intel Core2 E6600
• 4GB memory, two KVR800D2N5K2/2G kits
• WD1600AAJS 160GB HDD
• Plextor PX-755SA dual-layer DVDRW
• aOpen B200 case
• Samsung 244T 24" LCD

The press release from Samsung is dated April 2005. You can read more technical details there without all the annoying popups on ExtremeTech. Looks like the drivers which give the power savings were written by Microsoft. Planned ship date was late 2006, so they didn't fall too far behind.

• The Samsung tuner has an HDMI output with HDCP. HDCP will be needed to watch broadcast flagged content in non-degraded HD.
• Includes a QAM tuner for unscrambled digital content from cable (even basic cable).
• More outputs/inputs dedicated for television. Converting hardware and software not needed. No complicated setup process for outputs.
• Lower startup time. Simpler startup process. Simpler EPG.

That's not a bad HTPC solution, though, except for the low-capacity notebook hard drive and non-upgradable graphics (for h.264 acceleration and HDCP output). The upcoming Intel Santa Rosa notebook platform (which has been pushed up to May) might solve these limitations (except for the hard drive).

If you can find a Samsung SIR-T165, SIR-T451 or DTB-H260F, pick one up.

I have an SIR-T165 and it works great. Tunes all analog cable, OTA analog and digital, plus OTA HDTV. Supports all formats. No broadcast flag, IEEE-1394/FireWire, DVI, VGA/RGB, S-Video, component, composite. Samsung did a really great job packing in a lot of connectors, formats, and functionality. The SIR-T451 appears to add QAM for digital cable (in the clear, no doubt), and HDCP on the DVI.

This doesn't answer the question about where they've all gone, but Samsung did a good job and hopefully you can pick one of these, or something like it, up somewhere.

The downside to this model is its relatively short battery life, but it's even got a slide out qwerty keypad so texting isn't half bad...

Samsung's latest DLPs use high intensity LEDs to illuminate the DLP chip, not a standard bulb. These cannot (as far as I know) be burned out. Next topic?

Going for what single product review will recommend is silly. I rather go for infomration on quality in many reviews, collect thoughts that are very similar, discard that are wildly different, to get understand what the product is *about*, in terms of use and see wether I like it or not. My preference is with manufacturers that don't boost specs, on monitors, like Samsung does:

vs:

I don't know about anybody else, but the ability to add, tweak, hack, etc. my pda phone is one of the primary reasons I have the thing.

I have had a Samsung i730 for about a year now. I tried the i700 before that (though only for 13 days, and returned it for a regular phone since it was flaky). Thanks to sites like PDAPhoneHome and members like mrailing and sdave, the i730 has been made even more capable than it originally was. The ability to tweak and modify is essential.

I had my wife get a motorola 815 for this very same reason. Before the i730 I had a small samsung phone that I could tether to my laptop (or the mac mini while I had it, before the cable modem was installed) and have net access.

As sleek, shiny, and cool as the "iPhone" is, if they want to lock me out, then I just won't buy it. There are plenty of other options. Maybe not as cool looking (for now) as the iPhone, but a lot more open and flexible. Besides, what's the point of bragging about OSX running on this thing if they are going to lock everyone out of it?

Oh well, last night I told my wife I was going to be getting a cingular account in a few months -- guess I won't have to worry about that now, if this is true. :(

Apart from the eye candy, i don't see how this is anything revolutionary.

I agree. I recently purchased a Samsung BlackJack, and I'm a bit disappointed by the iPhone. I was hoping to be blown away (as I can still return the BlackJack). Here's how they stack up in the areas I care most about:

Dimensions:
Blackjack (inches): 4.45 x 2.32 x 0.46
iPhone (inches): 4.50 x 2.40 x 0.46

Weight:
BlackJack: 3.5 ounces
iPhone: 4.8 ounces

Advertised battery life (talk time):
BlackJack: 5.5 hours
iPhone: 5.0 hours

Camera (I don't really care, but the iPhone leads, so I'll give it):
BlackJack: 1.3 megapixel
iPhone: 2.0 megapixel

Both have push email. The iPhone isn't 3G, but it has 802.11b/g. The reverse is true for the BlackJack. I prefer having the 3G service, but that's specific to my lifestyle (if I'm in a hotspot, I usually have my laptop).

Now, of course, the BlackJack doesn't come with any storage for music, but with such a big price difference ($199 BlackJack, $499 iPhone), I'll pick up a Micro SD card and deal.

Oh, and I prefer physical buttons. I can use my phone without looking at it (useful while driving, for instance).

To Apple's credit, the iPhone does look nifty. I like the BlackJack's look, too, though. That's just me.

HL-S5679W is wobulated, and no, this isn't really a bad thing. The fact is that these wobulated sets virtually eliminate the SDE (Screen door effect) which is worth a tiny loss of sharpness to most viewers, and is what makes it "cinema smooth" or whatever buzzwords are used. Eventually they probably won't be wobulated, but I think this is more due to market pressures than due to an advantage of non-wobulated sets. BTW, the same is true of all the 1080p HL-S sets, though I'm not certain they all use the exact same DMD chips.

Yes, it starts up really quick. And it doesn't warm up (no big lamp, fewer moving parts).

20,000 hours is the official number, though a lot of people believe these sets will last more like 60,000 hours between having to replace the "bulbs". So, it's somewhere from 3-10 times the lifetime of standard bulbs. We still don't have numbers on the actual cost of these "bulbs" though, so a cost comparison is currently impossible.

This TV got delayed from April to May, to June or July, and then to September, though some dealers let some sets go back in August. The original MSRP of about $4200 is correct though prices have already dropped and you can find it for just over $3000 now, as I understand. Make sure to buy from an authorized retailer!

BTW, I think this is a great set, but it's worth getting a Samsung professionally calibrated (which can run you around $500) to achieve the best picture. At a minimum you should follow some recommendations and perform a user-level calibration, or you're really not doing these sets justice.

If you want to learn more then I recommend this thread on AVS Forum.

• Price
• 1080p
• Fear of plasma burn-in

I've had enough problems with LCD displays on laptops and handheld devices that I simply will not buy an LCD television until the manufacturer's dead pixel policy is something other than "It's not a bug, it's a feature!" I'm not going to spend upwards of $1000 for the device's manual to include a note in the Troubleshooting section telling me not to worry about little dots that won't go away.

With that said, personally, I just want an old-fashioned CRT, and I've been tempted by the likes of these. No rear projects or having to rethink A/V furniture, no young technologies that have new and interesting problems that have yet to be acceptably solved (be it dead pixels or greater susceptibility to burn-in), not even a rear projection, just good old-fashioned ions-on-phosphorous, and for a reasonable price. However, I'm relutctant to purchase even these because I've yet to see a direct view CRT that supports 1080p, and I see no point in getting a television that doesn't support features that will probably be worth having in the next ten years.

And speaking of "ten years," I want an appliance, not yet another piece of technology that gets thrown out after 3-4 years. If I cannot be reasonably assured that the television I'm considering buying will neither be obsolete in three years nor outright non-functioning, my NTSC set continues to work (from back when the most complicated question I had while shopping was "What kind of inputs does it have?")

No sir, my hard drive doesn't even spin that fast. You're off by orders of magnitude.

What does that have to do with DLP color wheels?

Considering that a DLP projector updates the screen 60 times a second, most color wheels spin at 60 or 120Hz. The early projectors had wheels that spun at only 60Hz leading to the unpopular color "shimmering" effect that prevents some people from buying it if they can notice the effect. Later wheels spin faster, reducing the effect greatly, but even these don't exceed 3x the display rate.

If the color wheel only spun 60 times per second, the picture wouldn't even be recognizeable. Assuming a 3-section color wheel, that means you'd only get green, red, or blue every third frame. Our eyes work much faster than that when determining color (motion can be synthesized with very few frames per second, creating colors out of sequential individual base colors requires much more than that).

I may be a little off with my upper-end range (30,000RPM), but 10,000RPM and above is actually quite common. For example:

• A randomly chosen current-model 1080p Samsung DLP: color wheel speed is 14,400RPM
• My year-old 720p Samsung DLP: 10,800RPM

High-end DLP projectors use three emitters (RGB), eliminating the need for a wheel entirely.

High-end DLP projectors, like those used in movie theaters, use three DMDs from a single light source that's been split into component colors via a prism. At least that's how it used to be. They'll probably move to three individual LED-based light sources emitting pure red, green, and blue. Of course they'll still need individual DMDs, which is where the expense comes in (and why consumer-grade sets don't use individual DMDs and thus need color wheels).

I'd say that HD capable computer monitors are not all that difficult to find.

Based on the euphoric reaction to PS3's flagship launch title Resistance: Fall of Man Sony has nailed this, the PS3 is a guaranteed long term hit. In spite of all the FUD (I wonder who sponsored that) the machine performs to spec and production qualities are top notch. Oh yes, I'm a PS3 fan. After all it is a Linux machine, not to mention a superb piece of engineering.

I personally won't bat an eye about dropping $600 on this box. After all, I'm picking up a $2,500 flat screen tv to go with it. Sony is obviously going to be selling every box it can make for a long time. Now the race to dominate the high end console market comes down to one thing: Sony's manufacturing ramp-up.

Rereading my question, I see it reads back thoroughly pedantic (rightfully slapped Troll). Sorry, it was just curiosity: I have earbuds that came with my Samsung but I really have to turn the volume up when commuting by train. I was wondering whether the Sennheiser earbuds were somehow designed to specially stop ambient noise.

I've wanted to invest in Samsung and flash technology in general. Samsung seems to only be on the Asian markets, is this so?

It's listed in London and Luxemburg too, and in the US, you can buy stock through Citibank.

It only took me a minute to find this information, it wasn't secret, hidden or hard to find. I only needed two clicks on the Samsung site.

Looks like Samsung and Microsoft designed this together.

Are there any other cheap yet effective cooling solutions for a small business where the budget is extremely limited?

Video systems frequently use a more complex approach referred to as interlaced video. Broadcast television systems such as NTSC, PAL, and SECAM produce an image using two passes called fields. Each field contains half of the lines in a complete frame (the odd-numbered lines or the even-numbered lines). Thus, while only using the bandwidth of 25 or 30 complete frames per second, they achieve a flicker fusion frequency of 50 or 60 Hz, at the expense of some vertical judder and additional system complexity. The "frame rate" of interlaced systems is usually defined as the number of complete frames (pairs of fields) transmitted each second (25 or 30 in most broadcast systems). However, since a conventional television camera will scan the scene again for each field, in many circumstances it may be useful to think of the frame rate as being equal to the field rate. In contrast to televisions, computer monitors generally use progressive scan, and therefore internet video formats generally do also. The "P" versions of HDTV (typically 720P) also supports progressive scan, as do modern DVD players.

I will admit that the ability to use my cell phone as a watch is nice. My current phone (Samsung SGH-c417) has the front screen, which I do use to check the time. And size was an important factor in my choice.
The problem is, one good bump and I expect that I am going to lose that screen. In order to keep that from happening I now use a belt holster for my phone, and I always make sure to put the phone into it with the screen facing my hip. I figure that my body will have more give than a table or chair that I might accidentally bump against.

Both the VGA cable and the Component cable do support 1080p. The only issue is that most of the 1080p TVs sold do not support 1080p over component. There are some exceptions, but generally they don't. But there's a lot more TVs that accept VGA and DVI, which will handle 1080p fine.

This still doesn't answer the ICT question of course, so we should assume that ICT protected movies wont work. It sucks, but the less DRM support around, the better.

So when you click on the link here, the text that says "Resolution: 1920x1080" is a lie? Or perhaps when I go to Samsung's website and click here and it says "HD-grade 1920(H) x 1080(V) pixel resolution", it that also a lie? I ask because I'm in the market for a 1080p television... and I thought I could take these companies at their word.

I was going through the local SuperWalmart a few weeks ago, and noted at least two CRT-based HD televisions. They were both in the 26-inch range, if I recall, and both were around $500. Froogle lists several, including the Toshiba 26HF66, Samsung TXP2675WHX/XAA and the Sansui HDTV2600 (A rebadged Orion, apparently, and I can't find a link for it).

It could play ogg. Let's start with that.

Then have it boot linux next year.

[The next generation iPod] could play ogg. Let's start with that.

This is quite offtopic. But, I have to agree. When I am looking at products, Samsung is always there and they are generally very good.

Such as this monitor I am using right now. It's the Samsung Syncmaster 940BW. I've had no problems with it... other than my video card is too old and can't push 1440x900. :-P

I have a samsung sch-a630 that uses CDMA on Verizon's network. Since Verizon uses cdma you should be able to use any of the phones that samsung claims are verizon phones. http://samsung.com/products/mobilephones/verizon/i ndex.asp I would suggest asking a Virgin Mobile representitive if they would be willing to activate a phone from that list before you buy it, I have heard on slashdot talk of vendor locked phones that will not let you switch networks.

It looks like flash is outpacing Moore's law, a perception reinforced by marketing and reality by the manufacturers of NAND, such as Samsung's roadmap images http://www.samsung.com/Products/Semiconductor/NAND Flash/index.htm.

In fact, the densities of nand units has continually doubled for several years, but only loosely tied to Moore's law. Moore talked about the doubling of the transistor densities, but if you do some simple calculations of the gate width and silicon lithography nodes, it is not truly following a doubling -- at least not at the same size.

Traditional lithography nodes scaled in 72% increments, which in two dimensions, is 50% scaling. If you track the NAND lithography nodes, they're moving at smaller and smaller increments. 90/70/60/50/45... these are not 72% increments, and thus, though the density is growing, die size is continually increasing.

The SLC to MLC moves jumpstart this a step; however, don't expect this to go on much longer.

I've had the Samsung ML-1740 for a few years now. Only needed to replace the toner once. Crystal-clear printing (b&w) (no color -- who really needs that?). Toner is around $80. Expect to find the printer on sale for $99 at your local electronics megastore, or $149 regularly.

I've gone through (no joke) about 10 different [ink|bubble|dot-matrix] printers and the Samsung printer is MUCH better than anything else. Even the more expensive Lexmark laser printers don't have anything on Samsung.

Oh, but this is for home use. For office use, it's a bit slow.

Best thing about it? You don't need to install any crazy drivers. Just plain vanilla Windows print screens. Nothing that talks to you while it's printing or stays eternally in your tray.

Here is a ZDNet Review], my personal review, and their specifications.

Well here's a 57 inch lcd tv
http://www.samsung.com/Products/TV/LCDTV/LNS5797DX XAA.asp?page=Features

I have a 32' lcd TV from Samsung and I've been really impressed.

Rear projection DLP is pretty good, and is less expensive than its alternatives. Whether or not it's appropriate for your requirements is up to you.

I just went to Samsung's site and selected the first rear projection DLP monitor that was over 50". I got this. Whether or not it's too deep is up to you. Samsung is claiming 16.3" deep in their specifications. Some are thinner than others though. As far as noise goes, manufacturers seem to be listening to what their customers want and are competing to make quieter units. You may want to go to a showroom and hear what kind of noise these produce. Also, plug a laptop into a few to see what your presentations look like.

It has been estimated that about 5% of people experience what is known as the DLP Rainbow Effect, where some viewers can see flashes of color separation on the edges of high contrast edges. To minimize this, manufacturers are speeding up color wheels and adding more segments to effectively increase the color wheel speed. As DLP chips become cheaper, I believe that we will begin seeing 3-chip solutions enter the consumer market to completely eliminate the issue. In any case, the rainbow effect is something that you may want to keep in mind when you consider whether or not to use DLP.
