Wireless mouse/desktop

[Demosthenes]

I just got a new computer with a wireless keyboard and mouse, but I was wondering if anyone knew typically how long the battery life on these things is.

Depends on the hardware. I'd reccomend a mouse that has a built in charger. (MX1000 or G7) With the G7, you have 2 batteries, so it'll never go dead.

As for keyboard..... iono.
