I was looking at mice today and saw MS's Bluetooth optical mouse.
I see that it comes with a USB bluetooth adapter, but I'm wondering if it's necessary with a 17" Powerbook (integrated bluetooth), or if it's just optional for those machines that don't already have it.
Also, what kind of battery life can be expected out of these? What kind of hit on notebook battery life will enabling bluetooth cause?
