Intel drives actually use the whole drive for scratch space. Until a sector is written to. Then without TRIM it only has its tiny bit of extra scratch space to work with. That's why intel drives degrade so badly without TRIM.
Indilinx Barefoot controllers on the other hand ONLY use their scratch space, they never use the normal writing space of the drive as scratch space.
See here.
http://www.anandtech.com/show/2829/9
While it does show the synthetic tests degrading with lack of trim, even more than the intel drives, the real world use tests show they suffer almost 0% loss in performance.
Depending on which controller the drive is using, TRIM could make almost no difference or a world of difference.
Anand explains it best:
"Only the Indilinx drives lose an appreciable amount of performance in the sequential write test, but they are the only drives to not lose any performance in the more real-world PCMark Vantage HDD suite. Although not displayed here, the overall PCMark Vantage score takes an even smaller hit on Indilinx drives. This could mean that in the real world, Indilinx drives stand to gain the least from TRIM support. This is possibly due to Indilinx using a largely static LBA mapping scheme; the only spare area is then the 6.25% outside of user space regardless of how used the drive is."
At the risk of being repetitive, this guy has hacked and released a TON of exploits which are only used for positive things for Apple iOS.
This in my mind makes him an expert, whether his identity is known or not, whether he sells apple products or not.
He, being an expert reverser, is also more likely employed in an engineering position at an electronics company than actually selling apple products.
Basically it comes down to an agree to disagree thing.
I have had many conversations with him and other members of the dev team (working on apple hacks myself) and besides his expertise, has only ever represented himself well.
It comes down to I trust him due to my experiance and his obvious technical expertise, and you cannot.
This has nothing to do with apple getting a free pass. The person I'm talking about has nothing to do with apple.
This is a hacker who I know is stupidly smart regarding the operating system who has inspected it and determined this is not the case. The claims put forth are not exactly hard to check. Hell the baseband is right in every ipsw zipped up. It isn't even encrypted.
That may be the proof you require, but for me, getting the word from the foremost expert on the subject outside the company engineers themselves is good enough for me.
Either way, code is not needed, just run a tcpdump and examine what is going on yourself, then you can rest easy if the results are positive.
As the AC said, it is who you trust. Basically, every hack for the iPhoneOS (iOS) has come from MuscleNerd, at least in part. His name is on damn near every one. He probably knows that OS better than some Apple engineers.
If he said he did code inspection and it's BS, then I personally believe him.
1. I've heard mostly bad reports about usability. Given one of my major complaints about Android is the unpolished UI, going to something like the N900 would probably be a step backwards there.
2. It is a dead end device. There will be no major upgrades to it since Nokia itself has said it won't be supporting Meego.
3. It only has AWS 3G bands, so on every major carrier here in Canada, I'd have no 3G.
As a concept though I love it, just a phone running linux. The thing is, with a jailbreak, I get pretty much everything the N900 gets except it's Darwin not Debian.
MuscleNerd, one of the, if not THE foremost Apple device hacker out there has implied he has done code inspection and just through common sense says its all BS.
There are a few tweets on the matter but this is one of the more telling:
I had a 3GS and figured I'd give something new a try.
Bought a Nexus One right from google.
At first it was 'ooo widgets' etc. The OS really is nice in some ways. Then I began to see the shortcomings. The UI operates at maybe 5FPS. There is a 2-300 ms lag when dragging the program icon menu around.
Then I tried to do my nerdly stuff with it like I did on the iPhone. BZZT. There is no gnu tools compiled for it, just busybox. WTF Linux phone and no gnu tools? Ok I want to SSH in...no OpenSSH. Some people have gotten 'dropbear' working. Dropbear really?
With my iphone I had full pub/priv key authentication set up, a bunch of scripts written for stuff I do on the phone, etc. I had a full apt GUI and command line for installing any tools I'd like as easily as I'd do on Ubuntu.
When I asked around why no proper environement has been built for the phone they just asked 'well why do you need it? Who needs ssh you have the adb shell'. It's hard to argue with people like that.
Between the lack of polish, slow UI even with a MUCH faster phone, and lack of an in depth Linux environement, it just isn't the platform for me, at least not yet. With the iPhone I really felt like I had a full computer in my pocket. I could almost replace my laptop if I had to (need an ethernet dongle!). I just don't (again, YET, android has a ways to go and I'm sure it will mature) with android.
I know it seems backwards, but the iPhone is the only phone I've found so far that really feels like a geek's phone, but ONLY once jailbroken. Without the jailbreak, I'd have the Android for sure.
Telus runs two networks. Their new HSPA+ (21mbps) network runs on both 850 and 1900 spectrum.
Rogers has both GSM AND HSPA/UMTS on 850 and 1900. Generally their 3G HSPA stuff is on 850 while the 2.5G EDGE is on 1900 but this is changing in many rual centers.
You can take an iPhone for example, and work perfectly fine on Telus, Bell, or Rogers (provided it is unlocked which they are from the Apple Store up here).
The particular phone you gave an example for was a bad one as well. The N900 has 2.5G EDGE/GSM on all Canadian frequencies. But it's 3G is only on the AWS band, which is T-Mobile in the USA or WIND Mobile here in Canada. You're also wrong about the SIM, Bell and Telus (and Nokia..what?) have their GSM network which has SIM cards like any other.
Telus/Bell still run their CDMA network but it is generatlly depreciated and not many phones are sold for it any longer.
SO basically there is no incompatible bullshit other than the info in your post. LTE will be welcome of course.
They list their model numbers as <generation>,<model within that generation>
The first iPhone was 1,1 of course. The 3G was 1,2. The 3GS was 2,1.
No idea what the iPhone 4 will be, but I'm guessing 3,1. So according to Apple, it would be the third generation of devices.
All of that being said, I consider things like you do. I think the jump from 2g to 3g adding a gps chip and new case design was more of a jump than 3g to 3gs, so bah to Apple.
Keeping in mind of course apple did not 'take away' anyones copy. If they later reaudit and change their mind, they just stop selling the app in question.
As the poster mentioned, it really is about that quick.
but.. "And changing that "option" doesnt void my warranty, nor start a cat and mouse game of updates undoing the jailbreak."
This part is a very valid point. It really is a cat and mouse game. Not the warranty part though as it is a software only mod and it is essentially impossible to truly brick your device these days. And if its bricked how could they tell? Unless you actually tell them you were jailbreaking there is no way for them to find out.
Sure evolutionary like the steam engine vs a modern porsche.
Have you ever used a Palm? You essentially couldn't browse any site, almost nothing worked. The PIM apps were decent of course, but playing mp3s was a joke, video was basically not possible, and the OS looked like dogpoop.
I mean, I had a 650, then 680, and I liked palm for a time, but how big of a jump do you really need to be called revolutionary rather than evolutionary.
The iPhone jumpstarted the entire industry from drivel like the Treos to stuff like the new Evo 4G and Palm Pre. I'm using a Nexus one right now, and I like Android, but like the OP said, you have to be a pretty rabid Apple hater to not acknowledge that Apple basically got the entire modern smartphone industry going.
I know you seem right when you think about it, but going faster than the wind is possible.
I sail for pleasure sometimes, and while I have not been on a boat doing it, the world cup type boats can sail faster than the wind, consistently, for hundreds of miles.
They are sailing into the wind, which generates lift using the sail. The faster they sail, the more lift is generated and the faster they go, until the resistance from the hull balances it out.
A world class racing trimaran can sail 2-3 times the speed of the wind, forever basically.
The only thing that makes me skeptical about the car is if it is sailing(it is still sailing regardless of the sail mechanism) directly away from the wind, it should not be possible to go faster, but I would not be suprised if there was a way.
Yeah unfortunatly the Apple-TV OS (some modified Panther or somethin) is a bit harder to get external receivers going but it may be possible. Might have to put linux on it.
Really I found it was the opposite. I quickly grew comfortable and discovered similar interests:D
Once you jailbreak the thing it is great, you get a nice full *nix box. You get a full BSD machine, with comprehensive apt packaging system, every gnu tool under the sun, an always on network connection, from a different ISP than your home for testing connectivity.
I'm using a Nexus One right now and it is no where near the hacker's phone the iPhone is.
You get a terminal kind of. It is busybox which has many gnu tools, but many options missing. Wanna SSH in ? Tough. Something called "Dropbear" is the only thing that people have compiled (no openssh suite , scp, nothing) and if you want it to work properly, you have to compile it yourself.
So I've found it more like the romantic comedy woman. You fall in love, bunch of shit happens that makes you want to ditch the bitch, then you get back together, see the inner beauty, and live happily every after.
I'm cheating on my iPhone right now, but I won't anymore I promise!
By itself the Apple-TV is pretty junky. You can buy stuff from iTunes store or rent etc, and stream your iTunes stuff over to it for easy playing, but overall not worth the money.
BUT, i threw a Broadcom Crystal HD (http://www.mythtv.org/wiki/Broadcom_Crystal_HD for some info) in it (replacing the wifi card which I did not need) and put XBMC on there and it is fantastic. Will play 1080p HD no problem, and damn near any format used in online downloading without a hitch.
This way, the features that weren't so compelling on an Apple-TV before are now great perks to my XBMC install. I can instantly rent a movie in HD if my download doesn't complete or the file ends up corrupt. If I can't find a move online, I usually can on iTunes. They are fairly complementary.
All in a tiny little box 7x7x1.
Only real disadvantage I've run into is the limited remote.

No, but the numbers on the knob read 1,2,3,4,10,10,10,10,10,10
It depends a lot on how the drive works.
Intel drives actually use the whole drive for scratch space. Until a sector is written to. Then without TRIM it only has its tiny bit of extra scratch space to work with. That's why intel drives degrade so badly without TRIM.

Yeah this is a total myth as the other poster said. Water has several peaks of absorption by frequency. The first peak is over 20GHz.
Water does absorb 2.4-2.5GHz but not especially more than any frequency around it.
Here are some charts to stare at for fun, water absorption vs frequency.

I thought about it pretty hard actually.
Three major things made me decide against it.
1. I've heard mostly bad reports about usability. Given one of my major complaints about Android is the unpolished UI, going to something like the N900 would probably be a step backwards there.
2. It is a dead end device. There will be no major upgrades to it since Nokia itself has said it won't be supporting Meego.

You're generally wrong.
Telus runs two networks. Their new HSPA+ (21mbps) network runs on both 850 and 1900 spectrum.

The only good answer for this is...
Apple itself calls thing a bit different.

No kidding. It is hard to feel sorry for them.
Don't you think on some level that these people should lose the lawsuit for supporting Uwe Boll with their time and bandwidth? I mean really.
Or use the word alledged. That's what everyone else does.
Keeping in mind of course apple did not 'take away' anyones copy. If they later reaudit and change their mind, they just stop selling the app in question.
Especially the weird shift between past and present within the same sentance.
As the poster mentioned, it really is about that quick.

I find Apple-TV to be a wicked XBMC platform.

I'm running a Nexus one right now, but come on. $40 cable?
There are cheap iphone cables and expensive micro usb cables as well.

iPhoneys? Grow up man, it isn't a contest.
Keep in mind that turbine and diesel engines have vastly different power to weight ratios though.
A 500hp Turbine will only be a couple hundred lbs, whereas the same diesel will be far heavier.
This should help achieve better overall economy given the same horsepower. Especially on smaller vehicles.
