Hello, I plan on buying a mac mini pretty soon but I have a few basic questions (I'm not too good with computers ) 1. If I bought a non-apple monitor, could i buy a webcam for facetime and photobooth to work? 2. Is the mac mini scaled to fit any size screen? 3. Can I still use USB's on my desktop and mac mini at the same time? ~ sorry if i sound stupid, I'm just not too good with this stuff. Thanks.
