And that's good???
I bought my Logitech mouse in June 2010 and use it every day for maybe 8 to 10 hours and I haven't changed the (non-rechargable) AA batteries yet.
Maybe I remember it wrong. I might have put a new battery in once. I don't think so, but it's so long ago I can't remember. It has been 3 years.
But 2 weeks??? That's pathetic.
EDIT: I must have changed the batteries and forgotten about it. The Logitech software says they are 90% full and have 2 years, 36 weeks and 6 days remaining. Sounds about right.
I mean, it's obviously not ideal, but it doesn't really take much effort to swap the batteries out. I've used Logitech mice in the past, but I wouldn't pick any of the ones on their website over the Magic Mouse. Their Touch Mouse seems nice, but it's only for Windows.
