Hello everyone! This is my first thread on MacRumors, and I wanted to say that this is a great forum with lots of info for us newbies. I have finally decided to become a switcher and leave the PC world behind. My first mac is on it's way and while I am (anxiously) waiting for my Santa Rosa MacBook, I am looking for a suitable mouse. As the MB only has two USB ports I was thinking along the line of a Bluetooth mouse. But this brings many questions regarding the use of one. How will it affect the battery of the MB? Will usage time be noticeably decreased? Do the mouse and MB pair automatically everytime I turn the Mac on? Or do I have to pair them each time? Can I use the BT mouse and a BT headset at the same time? Will the mouse work perfectly under WinXP in BootCamp? I know that's a fair number of questions, but I would greatly appreciate any answers or opinions. Thanks for your help.
