On the other hand, I believe it is bad for the battery to keep it fully charged all the time, hence my suggestion of a timer.

Alternatively, you could just turn the power off every now and again when you think of it, and turn it back on when the battery has run down to about 40%. (That's what I do with my notebook.)

I'm one of those saps who actually think that Wikipedia makes mostly sense, so this is where I got the mustard:

http://en.wikipedia.org/wiki/Lithium_ion_battery

There are basically only two things that will damage a Lithium-Ion battery: prolonged storage without any charge, and age. That's right: Li-ion batteries have this in common with us humans that they start dying from the day they were made.

There's more interesting reading on that page, but the main thing is that a fully charged battery at room temperature will die sooner than a half-charged one in the fridge.

If it doesn't explode, of course...
