Haha. I was just going to open a thread about it, too.
Well, I just installed it and everything seems to work ok although I haven't played with it much. The landscape keyboard seems to work without a hitch, so is shake to shuffle, and I really like the voice memo app, it seems nice and polished. FINALLY, a copy and paste. It took them forever to come out with this but it's now really as easy as one-two-three so I'll take it. Other than that, I do not notice much difference. We'll see how the MMS works once it rolls out. So far, I'm likin' it.
