I brought home my new 12" PB yesterday (or rather, my dad did) and I am LOVING it. I can't wait until I get my 20" Cinema to go with it! I have a couple of questions (more probably to be added later haha; I haven't really had a chance to play with it since I've had relatives over). Is a buzzing sound normal when the PB comes out of sleep or starts up? I think it's the HD; a fairly loud buzz, very quick, when it wakes up. Is there a way to turn off the BT keyboard/mouse without having to repair with the PB each time I come back? I want to conserve batteries, but it is a pain to have to BT repair each time I turn them back on. Can I use the $100 rebate on two separate purchases? I am going to send in the rebate for the computer and then later on (before June 25) I plan on buying a 20" Cinema display. Can I send one in for that, too? I know you have to actually quit a program to exit, not just hit the red x, but on Safari, if I hit the x on a browser window, will it close that particular window or do I actually have to hit "File > Close Window"? THANKS!!!!
