Im surprised you didnt install the leaked rtm few weeks ago.....its been a sweet four weeks, btw how do you like??
Naah, need my phone for work, so no experiments on that device

I really like what I'm seeing so far. The big additions are nice, but it's mostly the little things that impress me most. Things like buttons and UI ribbon placements etc. LinkedIn integration is cool too, but now I'm thinking I could use a feature to seperate the address lists (switchable between all and one of the other lists: email accounts, Facebook, LinkedIn etc).
I think WP7 was already the best, usability wise, but now it's miles ahead of everything else (my personal opinion - no flames pls

).
Unfortunately my biggest gripe wasn't fixed: having all appointments for the day scroll through the calendar tile.
Maybe Apollo, then ....
