A quick note for the terminally curious: the Rawhide nightly live build succeeded for the first time in 2011 tonight. If you grab the image from that link and throw it on a DVD or USB stick (too big for a CD at present), and you have co-operative hardware, it should boot up into a vaguely functional and very current GNOME 3 / GNOME Shell environment. (I'm not making any promises, though - it works on my Intel graphics adapter but not my NVIDIA, at present). Curious how things are looking in the GNOME Shell world right now? Take a look. Of course, there's still many tweaks and improvements to come before GNOME 3 and Fedora 15 are done - we're not even at Alpha for F15 yet - but if you just can't wait, go for it!
