My #1 opinion of the phone...
Compared to my OG Droid ... it just works.
Screen swipes work, answering calls works, etc. no more hoping the FC's cause the phone to reboot...no more crazy lag (yeah there's still a little from time to time)...oh and 4G is amazing.
So...bottom line...if you waited to trade in your OG droid you'll be very impressed. If you are coming from a Bionic, etc. to it...probably not so much...other than ICS functionality.
I AM coming from a Bionic (still have it for work now instead of play) and I love this phone.. today is day 1 but im telling you, in 30 days, the landscape for this phone is going to be 100% different. With an unlocked boot and no skins, the tinkerers are going to come out and play. Cyanogen will end up here, for those that enjoy it (never ran it, dunno).. Mom and Pop roms... 5 different kernel choices, 30 roms to choose from.. themes out the ying yang (i guess thats what im supposed to do...lol).. basically, options options options.... and we all love our options here in this forum.
