If you don't need it for gaming, and if you don't need it for work I would say at the moment Linux > Windows for the average user.
Of course people are scared because it's different than they are known, but for Office, Image, Mail, Browser, Messenger you have everything you need, and for the standard user it's more than enough if you don't need 100% compatibility to someone using MS Office or Photoshop.
But the big plus is the Software Centre, you just install what you need and don't need to find it from 3rd party sides, and more importantly (that's the '>' above) you get updates automatically and don't have Flash, Acrobat, Adobe Download Manager, Adobe Download Manager Manager [recent relevant xkcd somewhere], Java, Mozilla et al installing their own update routines and trying to transform your browser into a set of toolbars if you forget to unclick some checkboxes.
And you can c&p scripts form f.ds on how to search for your gamelogs...
Edit: I think the biggest problem is that you have to run some obscure script for some video codecs because of some patent issues before you can view all videos.
