But IBM is even having problems with their normal IDE drives...they need to fix those first! Also, why do you think IBM is getting out of hard drives. They just aren't good at it anymore... Remeber the 20 hour a day (i think it was) hard drives?
They are smaller and unreliable because...

The capacity is limited to the data density that can be put onto the platters. You have to realise that there are not as many platters, and they are much smaller. In order to get even the same storage size from a laptop hard drive, the data density would have to be much much greater than that of a normal hard drive. This means that unless they stop making desktop hard drives that have the highest density possible at the time, laptop hard drives cannot, and will never hold as much data as their bigger brothers.
Also, on reliability, you have to realise how much torture these little drives go through. They are banged around in your laptop case/backpack and moved while spinning. To keep it reliable, the manufacturer of my laptop drive says to only use the laptop on a stable flat surface (unmoving, not legs or anything like that) and to NEVER move the laptop when it is on. Your desktop drive never gets moved while on (well, the normal person never moves it), and is very rarely, if all, banged around (occasional lan party). In order to keep the angular momentum from being too great when they are moved, so they don't really wear out bearing and whatnot fast and to save battery power, they are made to spin much slower. A 10000 RPM hard drive wouldn't last nearly as long as a slower one, unless you never picked up your computer while it was on, or banged it around (just don't move it and it will most likely last as long as desktop drive, maybe even longer).
Also, fluid bearings are getting very popular with the newer drives. This helps to keep them from damaging themselves when they are banged around when off.
Why they don't use raid, I realy don't know. Most laptops support multiple hard drives (Toshiba), but most of the time they are removable. If you add another hard drive, where will you put it? If you have ever opened one of the newer (or even fairly old) laptops up, you will realise how crammed everything is. They are fitting a whole computer in the size of a keyboard. Adding another permanent hard drive, at least on mine, would require it to be quite a bit bigger (in terms of laptop size) because they would have to add room the size of the hard drive, plus some space for brackets. That would be about 2/5 an inch thicker. They could stack them without having to add much more room, but then you will have overheating, and once again, reliability problems.
And, IMHO, these are what they claim to be, desktop replacements, not server replacements. Why would you really need a SCSI or RAID configuration? The time you will save loading, compared to a standard desktop hard drive might only add up to tens of hours a year. To me, thats not worth the *reliability* or price, except for the coolness factor...heheh
They are just adding good cooling techniques (watercooled) that would allow for more compact cramming of parts. So now they don't have an excuse...:)
If you want something that will last, buy a toughbook! These things are garanteed to not break if dropped onto cement from arms length. But they are big and heavy and ugly as hell.
Do you want the touch points to be able to detect different pressures, or just on or off? In either case, do you want to be able to detect all points on the screen at once, or just a lot?
Playing on the other side of the country? From what I understand, this is going to be an adhoc type of scheme. Just console to console. They did say a mesh type network. So if they use a data hopping scheme (data hops from console to console until it finds correct one) which I doubt they will use, the farthest you could go would depend on the density of consoles around you.
Remember, for evolution, you have to have a mutation that is different from the norm, and the chances to have a mutation are insanely high. So the chances of having this specific gene mutate are insanely * insanely high...hehe
Alse, if this gene were not at all dominant, then it would probably not be included in the offspring.

Wouldn't a hefty switch work? I know that peak currents would probably be lower because of the formation of the arc (have to have the reed(?) move FAST!) and you will probably fry any electronic device within a couple meter because of the emmisions, but it could handle it.
When I say hefty, I mean something like a hefty screwdriver or crowbar (i know you'll be collecting all you life and get it to 1 or 2 MA) attached to a large spring, manually triggered.

I make multiple accounts (like I'm sure everyone does), one for spam and one for real emails. I'm very cautiouse in where I put my real email address, never anywhere that web crawlers can access. Put the address in an image if you have to put it somewhere (on your webpage).
One thing that you can do to find where some of these spam lists are getting your name is to put a unique name or identifier for the name section when you fill out any online forms (nomel(0), nomel(1), etc). When you get a spam message you will then be able to see who gave it to the spammer from the unique name. Sometimes it's surprising to find who gives out your info...:)
They have to realise that if the phone cannot find a signal...it simply increases power. So if it finds a signal after increasing its power to the maximum level (1 watt I believe), it will continue transmitting at that power...if you had a roomfull of this...I doubt it would be healthy...heheh
So if they want to block it...they have to _really_ block it.
I haven't seen any technical papers about UWB, and i have some questions.
How do you make the signal? Is it just a pulse at many frequencies (f, f+k, f+2k, f+nk) where f is the lower limit, and f+nk is the upper?
Also, looking at an article at UWBPlanet.com, I see "It can penetrate solid obstacles with virtually no degradation and has location capabilities that make GPS look like a blindfolded troll with a club. Furthermore, its location-sensing abilities are not limited to outdoor use in any way, as GPS solutions are." What kind of solid objects do they mean (metallic, I think not)? Is the lack of degregation because the frequency range is so wide that, if the absorbtion of the object is frequency specific (resonates, etc), there are many frequencies that do not get absorbed? It seems that they are being a little over confident...if your in a Faradays cage (building, or cage, heheh), you should still get poor to nill reception unless the wavelength of the signal was smaller than the smallest openening in the room (then of course you would be able to pick up a weak signal).
"Only a UWB receiver that knows the exact pulse sequence generated by the transmitted signal can in fact make use of the information in the signal" This sounds like some kind of frequency hopping scheme more than anything. Unless it used some sort of TDMA scheme.
Like it said. Identity theft. "Ok Mr. Smith, now to approve this credit card, and to have it sent to this odd adress, I will need your social security, blah blah blah..."
802.11b nics do not "remember" the last channel that someone transmitted on...so if there are many nics or ap's, the nic's have to process all of the data they see and filter what is meant for them and what is not, so packet loss will actually occur. This is a problem that we have at the employer I work for. We have many access points and nic's, and they just crawl when there is a lot of activity, and packet loss does occur. I know that there are people researching this, but it would require either changes in the standard, or changes in the hardware that might not lead to compliance with the standard...
This may be similar to what he is talking about...
If they do, they will be caught for all the code they stole from other peoples and companies software. I really think thats why they are putting up such a fuss about giving their code.
I wonder what % of M$ code is open source, and what % of that was written for linux...heheh

Because a watch is not only on your hand where it is flailing around all the time, but they require _very_ little power.
