I have a Mac. Best thing i have ever owned. Never have any problems with it, never freezes, never buffers for too long, applications are super-reliable, and it is a very user-friendly machine. It is amazing if you have a creative mind, and plan on doing Video-editing, photo-editing, or recording music (as i do). I have the desktop Mac, and am currently saving up to get a MacBook, because they are just that awesome.
The Mac is amazing. Save up the money, and get one. Way more reliable than Windows.
