What is the coolest thing about your mac? I just got a new iMac 27" i7 this past weekend. My first mac ever, and the few hours I've spent on it have been very enjoyable. The multi-tasking is amazing, the apps are cool and the screen just blows me away. I've read a lot of the guides and posts here at MacRumors and they are all very helpful. But I'm still curious what gets everyone so excited when they turn there mac on everyday?
