I wouldn't like a lithium that was built in, but ones that can be
removed and recharged are fine really.


Just beware that some firms, like Panasonic, are locking their firmware
so that you can only use "genuine" Panasonic batteries and not the often
better aftermarket alternatives. That's OK to start with, but when you
decide you want a spare battery to go camping with you find they screw
you right-royally.
