In this application, NiMH cannot power a mouse as long.
NiMH inherantly has a self-discharge propensity that will
result in lower usable power over the course of several
months time. If the mouse were power hungry enough that it
drained the batteries within a month or two, NiMH would be
more competitive.

That doesn't mean it isn't a good idea to use NiMH, as
certainly it'll be more cost effective and kinder to the
environment. The remaining option that somewhat contradicts
what I wrote above is the new breed of NiMH by Sanyo,
eneloop. Their capacity is lower than their other NiMH but
self-discharge rate is much lower. Unfortunately most
places don't carry eneloop yet, of the major retailers they
might be cheapest at hhgreg.com
