DL'd and upgraded OS successfully.
In addition to what everyone else has remarked I would add just a few things, possibly unique to my device, but maybe there are others out there who experienced the same issues:
When connected to the computer the custom ringtones/alerts did not work. I have already received a call while connected to the computer and to my surprise (post update) the phone rang!
Answering the phone with touch screen actually works (no need to click 3+ times).
Generally one click works when doing anything. Previously, clicks would not register the first time.
Keyboard now displays the word "espacio" instead of space when typing in Spanish.
Pictures definitely load faster!
Overall, I am very pleased with the performance!!!
