This is something that has bugged me for many years! I am an
industrial designer and whenever I got a project that was battery
powered I tried to make sure it would work with rechargable
batteries, but it has been an up-hill battle.

AFAIK it seems the big problem is the voltage output of rechargeable
is usually slightly less than non-rechargeable so the electrical
engineers balk at adding one more battery to the package to make up
for the difference. In very small products one extra battery could be
a project stopper. Until the rechargeable battery industry is able to
make higher output levels (or the other electronics/electrical parts
are designed to work at lower  voltage) this will continue to be a
problem.

Not that it is a great solution, but many cities  now have battery
recycling stations - in California is is now illegal to put batteries
in the general trash (but enforcement is a bit weak...) http://

Another tangential problem is the number of different transformer
packs, plug-ends and adaptors that are needed to run all those small
devices. The so-called "universal adaptor" I got at Radio Shack for
my Vanagon is anything but. And think of how much power is being
wasted by all of those transformers!
