I beg to differ regarding AV/anti-spyware. I sincerely believe that it's important to run these when on Windows, especially when connected to the net. A user can easily get infected SD cards or even mp3 players from friends -- let alone the internet spyware.
As for the height of the windows. While Linux might have a shortcut about this, it also has more apps that require the shortcut. On Windows, these [popular] apps that would require it are fewer. So it's a trade off. Edited 2008-09-17 01:17 UTC
