Have to admit linux has become usable finally ...
using it a lot for my thesis ... Gnome 3 is really a great desktop manager, it's neat looking and from a usability pov it"s better than Win7 imho ... I also get to like the VI editor ...
but still a lot of commercial software is only available for windows, so I will still use in windows in the future ...
but still linux has finally become usable for the desktop ... if there was enough software available I would definately make it my main os ...
