I got the update yesterday. I'm liking the new additions. Notably the PVR ascending/descending option, removal of unused icons in the menu and 1-click recording.
I haven't really played with TV Roaming, but I'm sure it will come in handy at some point.
Grid guide colour wasn't high on my list but still nice to have.
Seeing I record everything I watch Reminders wont be used much if at all, but again, nice to have the option should I wish to.
One of the fixes I'm happy to see is:
"Clicking on search doesn't have a 3 second delay to display the keypad anymore."
Very nice! (It annoyed the hell out of me.)
