After years of trouble, viruses, blue screens of death etc. from my various PC's i made the best investment i have ever made. They say once you go Mac you never go back. Purchased an iMac in 2008, never have to turn it off (just goes to sleep) never have virus problems, SOOOOO quick to download/upload, after a couple of days of use to get used to it, it's actually far easier and more user friendly than Microsoft, heaps of free LEGAL software you can download and for those that need their hit of Microsoft (i hate MS personally) you can by using a program such as VMware Fusion.
