Anybody ever run the numbers? I have A LOT of friends at work riding me b/c I bought the iMac. They can't deter me, I love that thing. Does so much I can't begin to preach to them. Anyway, their main argument is that I overspent saying I could get a comparable PC for much cheaper. I don't believe it but need some numbers. I saw Dell's 27" LED display today for $1100 and that's a good start... By the time you add WiFi, Bluetooth (receiver/keyboard/mouse), equivalent software,.... How much? I'm not much of a build-it-yourself guy so I need your help!!!
