I used Win 3.11 a while, but I didn't like it very much, so I managed my things with Dos Navigator. Win95 OSR-2 was a wonderful OS until Win98SE came along. I used it until WinXP+SP1 came out and I liked that too. Now I'm using Win2k3+SP1 and I love it. Vista...? I'll wait 'till WinFS will be implemented (probably SP1). IF they will implement WinFS in SP2 of Win2k3 I'll never switch to Vista.
