Those of you out there that have one - is the battery life any good? I'm debating getting one... Thanks!

I have heard that the battery life is pretty decent, but you just have to remember to turn it off when you are not using it. There is a small slide door at the bottom that covers up the optical censor when not in use which turns it off. If you are using it as a desktop and want it on ALL the time, the battery life is not that great. A standard wireless mouse would be better in this case than the bluetooth one. However if you are using it with a laptop or don't mind just flipping the switch, it lasts very good.

What's "bettery?"

One month for the mouse
And my keyboard is always good so 2 months

just get a nice pack of rechargable bad boys... and you'll be set.

One month for a cordless mouse? sure?

I own both, the Apple Wireless Keyboard and Mouse and say that's just about right.

But, still at that rate, recharable batteries would not only be more convenient but more economical.
