The UI on 2.0.1 seems snappier than the 2.1 ROM. The live wallpapers look neat, but the one I really like, Nexus, is non-functional... and the animated ones suck battery life. Too many of the screens do not switch to landscape mode. These include the home screen when car docked, messaging. The application list screen gets all wonky in landscape too. The "back" history seems to act unpredictably. The phone rebooted spontaneously 4-5 times over the week. The hard keyboard backlight fails to work more often than works. Aside from these issues there are other random UI anomalies and quirks.
