Something I think you should all know as well, fuel cells produce distilled (pure) water. Distilled water does not conduct electricity. Only when compounds that ionized when dissolved are added to the water does it conduct. As others have stated, unless there is some safe way to eliminate the byproduct's (evaporation, re-addition to fuel tank, waste tank etc) the techonology is not going anywhere.

A Windows warning box pops up on the screen stating, " Your Windows Mobile device's bladder is full. Please take it to the nearest lavatory for fluid excretion. "
A service complaint... My device has a "weak bladder" and has to "go" all the time. :)
Since the amount of water is miniscule, why not use that water to keep the device cool. I know that if I leave my x30 on a fabric mat, the unit (maybe the battery) heats up. Perhaps a radiator component to keep the device or CPU/memory chips cooler. I think that this would benefit laptops since the heat generated is one of the complaints (at least for me).

everyone bitching about not finding fuel...chemicals in your pocket...etc...do you understand what batteries are? caustic chemicals you have to replace...
as for charging, there's a good chance itll be cheaper than the electricity youd use to charge it, and oh no, 3 seconds of holding a plastic bottle to its fill port, you wont have the 5 hrs of wait like now but you have to DO SOMETHING
and if the water byproduct amounts to anything, we can always use it to keep ourselves hydrated on a summer day...
heh... The waste water could be heated by a little built in coil. Then you could have little filter coffee bags, and you could drink coffee out of the side of your axim all day.
The energy density (critical for small devices) of methanol is 22MJ/Kg. The BEST lithium based batteries are just peaking over 1MJ/Kg. The reason cars are moving to batteries is that power consumption in a car demanded high energy of fuels for along time, but technology has made it so batteries can meet the energy needs of the car.
The reason cars are moving to hybrids is that the fuel energy of gasoline plus a small engine is way beyond the weight/volume of an equivalent power output of batteries alone. Battery power alone has proven to be inadequate for the flexibility most drivers need, because the range of all-electric cars is highly limited, because even with a trunkfull of batteries, electric cars still don't have anything near the equivalent energy density of a gas tank. You can't instantly recharge them with a quick-fill at the local filling station either on a long trip.
When fuel cells for cars become practical, then the hybrid design won't be necessary.
And the reason that even hybrids are practical, is that for steady speed driving, cars don't need to use much energy. It is acceleration (getting up to speed, driving in a headwind, or heading uphill) where most of the power is used, and hybrid mileage declines rapidly in in-city and stop and go traffic.
The primary convenience of a fuel cell, is that it's an "immediate recharge" system. Yeah, plugging your Axim in at night can work. But if you're using it all day and night, it runs out of juice. If the battery is methanol based, it'll both run a long time, and if you have your supply of methanol handy, you can recharge it in seconds instead of waiting for hours. If a single battery currently meets your needs in daily use, than a fuel cell will last for weeks without a recharge.
Incidentally, the reason why lighters are banned on airplanes has nothing to do with the risk of flammability of their fuel. It's because some idiot put a bomb in his shoes and tried to light the fuse. From there, it was speculated that a lighter could be used to start a fire in an airplane cabin. I don't know if matches are similarly banned, but from that logic they should be. In any case, it's the fire making ability of lighters, not the inherent flammability of their fuel content, that is the risk factor.

the reason this isn't here already is because given current abilities it is not feasible
If they haven't figured it out in 15 years, I doubt they will ever.
OLED displays are another example of hype that is always around the corner, but is never here.
Prototypes one one thing, but it they could do this cost effectively they would have already by now!
they said the same about regular LCDs...
i lived with a guy who did research on OLEDs...they are MUCH further along than the general misconception. right now, the big thing is perfecting printable electronics...he told me that right now, they can convert a standard large-volume press to two-color LCDs and in a week, print the worlds supply for the next year or so...
honestly man if you don't know what you're talking about, don't. we haven't cured AIDS or even a cold, but hey its been 15 years lets give up. clearly they shouldn't have developed optical media or microprocessors, they took more than 15 years to develop!

Ummmmm, as far as I know OLED is here now. The Tech/Gov/Business I contract with is having a feild-day with it. Its just not "Here" as you say because its still a little on the exspensive side. Sony is doing some great development with free flowing screens that can wrap around objects (like your wrist) and combined with a touchscreen interface...
No OLED isn't everywhere yet but that doesn't mean its vaporware. But I guess you wouldn't mind paying a few hundred grand for your new OLED monitor when LCD is dirt cheap right now. Can you buy me one?
BTW: look at how long the computer was in development. 15 years is a relatively short period of time.
