Just got mine today after looking at my phone the first time. Looks pretty good obviously and the landscape mode is definitely more functional, but other than that can't tell see much of a difference.
I have been checking my phone for the update every hour on the hour since the this post went up. I do not know what I am going to do without the new market update.
I am on a Sprint Epic and have just got the new market automatically without a say in the matter, whilst I was updating an app... I really do not care for the big green bubble waste of space at the top...
