A pretty interesting article I found not too long ago. It's written by a graphic designer, who obviously owns a 360, and is a bit worried by the look of the 360's dashboard. So, what else but to make up a concept of a better dashboard?
Personally, I think it would be a good idea to give the dashboard a nice upgrade, plus his additions (mostly the 'user ratings' and 'show me the money' sections) are pretty novel ideas. Sadly, I doubt any of this would get added, if any time soon. Still, it's nice to dream.
