And yes the newer technologies are getting rid of a lot of problems.

I have not seen what is in the Jetbook spec'd
Most all of the units designed for rechargeables these days use lithium ion or a variation there of. These batteries like to be topped off and can be topped off many many times. Unfortunately the chemistry results in batteries with more than 1.5 Volts so they cannot be used for AA cells, although sometimes a battery pack simulates two AA cells side by side.

AA cells use NiMH cells which are better to let run down before recharging since they typically have a finite number of recharges regardless of how far down they are. The newest technology in NiMH cells has solved the self discharge problems with rechargeables and are much better it you leave them in the unit for a long time without using it.

NiCads are only good for solar charged lights and high drain devices like an electric drill these days. They still have problems with the memory effect.
