[OLPC-devel] Battery Charge End Sensing

[Jim Gettys]

Actually, Mako Hill has made a Tamagotchi game to help encourage kids to
optimize their wireless behavior.

We'll probably end up with considerably more capable battery information
than most machines, as far as I gather.

So maybe there should be battery rewards for good wireless behavior by
the kids as well.
