Before the list, let me tell you. I don’t know why I waited soooo long to get a Mac (this is my first one). I had an old PC that ran all of those background tasks and that operating system they call Windows. I was living in hell. I bought the iMac in early January 2010 and I can safely say that I will die before I go back to a PC. The GUI is amazing, the speed and agility this computer has is beyond my expectations. I have no problems popping up 6 different programs with 18 different websites open in Safari while jamming out to Metallica, and with the below widgets all at one time. It is amazing. Not much else I can say. It was worth the 2,000 (including a 3 year maintenance plan and 500GB external hard drive).
