Is it really a blind test? I can't see any results.
The video begins like an advertisement, continues like and advertisement, i'm not sure i can trust it, it doesn't look like it was done by an independent company.
I'd love to see the results of a usability test between OSX, various flavors of Linux, and varios versions of Windows. Asking first time users to acheive simple tasks like sending and reading email, using the web, storing and sharing pictures and listening to music.
