Got the update Friday and honestly, thus far, I'm not impressed with it really at all. I really liked the way the revue worked before and as of right now it does exactly the same as before but not as well. if given the chance, I would revert back without a seconds thought.
The things I do like about it is sideloading, although for the most part, this hasn't been terribly beneficial in any way. I am in no way happy with the new home screen launcher so I sideloaded ADW and I like it more although it has a very gingerbread feel to it now, in terms of layout.
The things I miss mostly is the, and I can't exactly remember what the name of the tab was, "what's on" section. The new app is sluggish compared to the old menu and although it has more eye candy it takes a lot more steps to see what is on tv at a moments notice. This was a huge benefit for me because it was a million times easier than going through my cable providers cable menu's especially since I don't watch much tv and have no idea what's on at any given moment.
So to close, I'm not saying it's a bad update just that it didn't really bring anything to the table for me at least and that I'm slightly disappointed. My daughter is actually more bummed than me and she keeps asking me if there is any way to revert the device to gingerbread. /shrug :-\
