That's been the holy grail for portable computers for ages.  Getting a
unit that could run for a week on a charge would probably take the
market by storm.

It seems that every time there are advances, the systems are redesigned
to consume more power.  A 10-hour charge is the minimum needed for a
solid day at a conference or the misery of air travel.

IMHO putting a solid state device like one of the old zauruses, with a
decent screen and resolution inside a 14" chassis would leave a lot of
space for battery cells.  There are a lot of standard-sized rechargeable
batter packs available off the shelf.  At worst, a 14" chassis about the
form factor of a G3 macbook could hold several redundant banks of
c-cells just like your average ghetto blaster.

Granted the zaurus could be called under-powered by some, but even if
you take a smaller 9" unit like the Lemote Yeeloong and put it in a 14"
case, there is space for more battery.

The solid state hard drives are still rather small, but I'm wondering
what ever happened to the Coda file system and if, between the
availability of wifi and 3G modems, it could be used to compensate.
