One big advantage for battery operated devices like the jetBook Lite is that you never
need to wait while the batteries are charging, you just replace the drained batteries
with ones that you have already charged up. You could even use primary (non-rechargeable) batteries in a pinch. A set of four NiMH rechargeable batteries costs
about $10. With two sets and a charger you can always have a charged set ready to
go long before the set you are using runs out.
