My sister has Win 7 on her laptop so I get to use it many a times. The difference is when she had windows vista I used it to solve her problems and now I use it when I don't want to boot up my own desktop. I am beginning to think win 7 is the best OS by MS after WinXP SP1. It boots up fairly fast, it does not crash much, never hangs. The only problem is not every game and software is compatible with it.
