GNOM3
Ok, so it’s “GNOME 3″ but my title looks better…anywho, I’m sad that it got pushed back from full release, but I’m thrilled at the progress that’s been made. It reminds me a bit (in a good way) of the “Remix” and “Netbook” versions of some GUI’d recently, which I honestly think is a great way to go. That may be due to my belief that an iPhone sized device should be able to hold all of the data you’re working on and be able to work on it, and when you need a bigger screen you just plug the device into it…a man can dream, ok?
