The Zeos PPC is not backlit, uses a CISC chip, and it's battery life is only
8
to 10 hours. Asside from the processor, there are a lot more chips in the
box
that draw power.
Handwriting recognition is a very difficult process, and requires a LOT of
CPU
processing, even coding in fast assembler code, you are still going to need a
FAST processor to handle all the data. The faster the processor, [regardless
of RISC or CISC] the more power it requires.
There is an old saying "Fast, Powerful, and Cheap: Pick Two" I think it
would
apply here as well.
