Wow what a difference, this machine blows any windows machine I've had away.... Got the wife a MacBook a year ago, I never used it much then my Desktop got a trojan from my wireless AP dashboard website that slipped past my AVG av..took forever to get it removed and had to purchase other software to get it off, then machine never performed well again..so to hell with windows..did the switch got Windows office for iMac so I can still write work related documentation in Word, do spreadsheets, etc..I'm set!
