I wish you could have cribs and such - have your avatar walk around and visit other cribs - and even trash your friend's spot - like in Animal Kingdom.
I do like the NXE and will try the Home beta. However, streaming movies is the bomb and I definitely look forward to seeing what else MS has coming down the tubes.
@ Halogamer - even though we are political ying-yang, I think your avatar is a mess. It's funny and I like it.
