Hello, I recently bought an iMac 20", my first Mac, I absolutely love it, but there's also a problem. Every time I shutdown it (I need to use Windows for work and university) and boot it up in OS X, it just takes so damn long.. Even my Windows XP boots faster.. OS X itself boots pretty fast, but then there's a big slowdown for some minutes.. for what ? Didn't know that loading Skype, Colloquy and Mail takes so much system resources and makes my hard drive go berserk.. This is really annoying, I thought Macs should boot lightning fast, guess I was wrong..
