Find an all-in-one computer with 64bit Linux with a 3.06GH, Core2Duo Intel processor, 4GB RAM, 500GB HD, with a 1920 X 1080 21.5 inch LED lit LCD screen with 178º angle of view screen both vertically and horizontally with 320c/m2 brightness Monitor, wireless keyboard, WIFI and Bluetooth built-in, built out of a single block of solid aluminum that sells for $1200 and you tell me. Or, you could install LINUS on an iMac and compare. I suspect, that since OS X is a certified UNIX, that the IMac would blow the LINUX away.
