Overall the screen size is perfect, coming from the Dinc it seems huge at first but is perfect sitting on my desk. First off, there is a small amount of lag or stutter when pulling up menues or changing home screens, but i mean small, nothing that makes it unusable or even very noticible, but it is not quite as smooth at the 3gs.
Colors look just a tad washed out but i have not played with pretty much any setting at this point.
I did connect it to my Eclipse CD player in my truck and it connected first try, and stayed connected.
Ran google maps with no problems, only thing is i was on the phone and the navigation voice came thru the headset speaker, the caller did not hear it so no big deal, just surprised me. The "home" button does wake the phone.
I am not sure how i feel about the actual physical buttons, as long as they dont crap out i think they will be good.
Pictures are great, just snapped a couple of a house and an employee commented on the clairty of the pics when i got back to the office.
LOVE the ability to resize the widgets. I do miss the Sense widgets for bookmarks and friendstream but will have to find alternatives.
THE BATTERY SEEMS GREAT. came 70% full, ran GPS bluetooth wifi, pics, 15 min of calls, played a little, web over wifi all that for about 2 1/2 hours and still at 50%. Dinc would have been half dead already under those conditions.
I was also orig worried about the bump in the back where the camera is but it is not nearly as noticible as some of the pics make it look. It is actually very nice becuase my finger rests under it and gives it a place to rest naturally
I know these are just ramblings and my first impressions but i am very happy with the phone and not hesitating the purchase at all. Took it into a verizon store and they were blown away, the employees there had not even seen it yet. needless to say there were no invisishields ot cases yet. i am trying to fit a HD2 screen shield today for temp use.
