It's been 25 years to the day that Microsoft released the first version of Windows, and while I am very much an Apple fanboy, I still use Windows on one computer, and have a fondness for it even if it drives me up the wall sometimes.
After dealing with Windows 98 and Windows ME (aaaiiieeee), I was most grateful for the joys that Windows XP brought us. Vista had its issues (understatement much?) but Windows 7 is pretty damn good.
It's still no OSX, though ;)
Anyway. My point is that, while Windows sucks at a lot of stuff and frequently conks out for no real reason, I'm still glad it's around. Happy birthday, blue screen of death!
