Just in case someone didn't want to be first...I've upgraded successfully, moved my apps to my SD card for some breathing room finally! Everything went smoothly, and there are quite a few steps to go through, but it all went great!
Just finished. Little over 10 minutes, not too bad.
Edit: Minor gripe, they changed the charging sound I've been used to hearing for the past 3 years. Hope I can get it back.
10 minutes, really? Mine took about 90 mins!
