Quite honestly I don't really understand all the fuss about this battery or that battery, etc... As long as the product works reliably given the battery choice that was made, it should not be that big of a issue.
Originaly people touted CompactDrives use of AA cells because you could go out and buy Alkaline cells and use them in a pinch. We know know that isn't really practical because Alkaline cells will only last maybe 2 or 3Gig of transfer at best, now I guess how much of a pinch you are in, may determin how practical this is, but if you've got a 4GB flash card, it's clearly not practical...
So, now you can choose between NiMH AA rechargables or Lithium based non rechargable... But you'll probably be hard pressed finding Lithium based non rechargalbes at some remote drug store in nowheresville wherever... But if you plan ahead and take the approprete batteries and/or chargers with you, the choice of AA cells is perfectly fine.
On the ohterhand... Many common devices, phones, PDAs, PSDs, cameras, etc... that all use LiPo rechargables. Many of these devices have built in charging systems, and some merely require a DC voltage input from say 5-30 volts in order to 'charge' their batteries. I personaly have had very good sucsess with many such devices... I've got a Sony TRV900 that I've owned for about 4 years now, and the origianl LiIon battey that came with it is still working just fine. The only LiIon battery I've owned in the past 4 years that has died completly is a cheapo BP511 nockoff... The original Canon BP511 that came with my DRebel still works just fine after two years of use. The main bennifit to LiPo is size and weight per mAh supplied in a rechargable battery.
Bottom line for me... the choice of battery a PSD uses is not at the top of my list of items I look for when shoping for the ultimate device for my needs.

I've got my eye of a new Canon A700, if I get it I'll be using
Lithium batteries, not NiMH.

I suspect that most people who carry a PSD don't actually use it on
even a weekly basis. NiMH loses charge quite rapidly so you have to
keep up a frequent charging regimen to keep a PSD charged and
ready. Lithium ion has much longer charge retention and is better
suited for a device that you're going to use intermittently.
Perhaps they could be coaxed into offering two models. The
engineering was already done for the Li-ion version.
