I had written before about the Galaxy Nexus; I've upgraded it to Android Jelly Bean, and so far loving the new notification framework, and the overall smoothness and perceived speed jump in usage.
The ability to mass dismiss notifications is also quite cool. Not cool is the auto-resizing / scaling of widgets. Sometimes, you want widgets to stay just where they are dammit, and this sometimes gets in the way. Pity there is no way to "lock" a widget / home screen.
Time to go play and discover more :-)
