The LiIon batteries are fine-- as long as you never intend to need to
use it for a period past it's battery capacity. The only advantages
of NiMH is you can carry extra cells to cover any length of field use
you need, and replacement cells are cheaper.

NiMH last longer than you will probably want to keep them. 2-3 years
might be a good guess of lifetime, assuming average (meaning somewhat
abused) treatment and use.
But, with NiMH battery capacity increasing all the time, you will
probably buy a new set every year or so, and use the old set as a
backup. I'm planning just this; getting new 2300mAh cells, moving my
current 1800mAh cells to backup position, and retiring my original
1500mAh archos supplied cells.

It's a real concern, if you are thinking of keeping your JBRv2
long-term. But chances are, you will throw it away before you have
problems finding replacement LiIon batteries. I plan on keeping my v1
JBR for many more years, so I'm glad I have NiMH as a battery choice.
