Working now after giving it a few minutes to settle down, sync and do whatever background tasks it needed to do.
-Web browser is a bit faster at page rendering & scrollling through large desktop-formatted pages.
-Automatic brightness setting in the power panel widget is very handy
-Phone app switching seems a bit laggier than before
-I had to reinstall the Weather Channel widget for some reason
-5 homescreens rock!
-Accelerometer seems a bit sluggish
-Love those new shortcuts on the bottom for phone & browser
