First impressions: It's great, smooth and looking a lot more polished than previous releases (GB/Froyo)
Favorite changes. App button back in the center and looking better, the overall dark look and feel, how much faster it is, the new voice recognition, the new and smaller menus!
Performance Performance is was great to begin with, now its even better. I use the "forest" Live wallpaper and it runs without ANY lag now. It actually looks turbocharged when the rain drops are falling
Enhancements. Oh heck there are tons!
Issues.Currently, I can't use tether with WiFi tether or FoxFi... Nothing works. I can't find where to set double tap the home button does XX action.
What seems missing or could be better.
I like that widgets are now in a nice new fancy window, but I HATE that you have to scroll through every dang one to find what you want. Everything with "beautiful widgets" should be located under one location like in GB. You pushed Beautiful widgets then you got your list of 8-10 widgets to select. This would clear up clutter in the widget list, and also for items that have long file names, you'd be able to see it better.
The ability to remove unused screens.. I only want 2 homescreens, I don't need 5.
Pulldown notification toggles for wifi restart power gps bluetooth, etc.
