They look really nice, but functionality is still lacking to make them a daily use ROM.
Some of the options that are included, though - wow. Things like a super uber Power control bar, with options depending upon whether WiFi is on or not, if you're plugged in otr not, etc.
The ability to use sound / vibrate / silent independently again (and the ability to choose if you want other ways, like just sound (with vibrate always on) and silent, just sound and silent, just sound and vibrate....
It has a lot more backend changes in it than I expected. A lot. All the folks trolling the Google code report pages are in for a huge surprise - especially the ones acting like kids and saying things like "How long does it take to fix this it's been XXX days already! Google, you suck!"
I also like the dark look to it - much nicer than regular, although that may be because I ma using the GB based off of CM....
Finally, the one I tried seemed to have the older, pre-FroYo market in place - not sure what was up with that either. My guess is that the final GB will have the final set of new components and we're gonna be wowed even more.
