I am not sure yet. Too early for me to draw any conclusions. I am especially concerned that the phone might revert back to disconnecting from WiFi when it is idle for a while... I HATED THAT. These are my observations after just an hour:
* After the update, I was missing some widgets and still not quite sure about one blank area... what was that?? Also had a strange, mis-sized bookmarks widget that I could not completely see on the screen or even adjust. I eventually was able to delete it and re-add and that fixed it.
* I can't believe it is almost 2013 and HTC still does not allow for a landscape unlock screen nor a landscape home screen. STUPID, especially since the code is already there for dock mode.
* I am disappointed the wallpaper no longer scrolls. It is not a big whoop, but it was a nice touch.
* I hate that the carousel wraps around. It makes it easier to get lost, and of course there is no setting to personalize that behavior.
* I hate the "Power Saver" in the notifications bar. I don't understand why there is no way to get rid of it and why they think that is so important. The checkmark to turn off notifications in that app is not uncheckable, and they made the app non "DISABLE"-able.
* I hate that there is not a dedicated voice button on the keyboard.
* The Gallery app is even more irritating than before. Not only does it STILL not understand how to deal with multiple nested directories, I am FORCED to go through yet another menu with "cloud" sources that I do not want to see or use (no way to turn it off). Thank God for QuickPic.
* Love that there is an option to FINALLY turn off the stupid non-security lock screen so we can FINALLY just use a secure lock screen ONLY. It is insane that it took this long for HTC to fix this!
* Could be my imagination, but it does seem that the user interface is faster.
* The pinch-zoom on the camera is neat.
