This is really stupid, but the computer + monitor I have right now doesn't feel like a "real" Mac to me. I have a Mac Pro and an Asus monitor, but it just feels like a PC. I don't know why I feel that way, and it's stupid because it almost makes me regret getting this and selling my original iMac but at the same time I don't. I don't know. Please tell me someone else has felt this way so I don't seem crazy.
