well its not as clunky as Windows 6.5 on the samsung omnia (hopin for win7 to be better) its not as laggy as the blackberry storm or the LG Dare. It scrolls nice, moves nice, camera... meh (compared to the omnia which is omg amazing best camera i have ever seen on a phone) qwerty keyboard is nice (used to omnia touch screen), wish it had gestures like the iphone for zoom and pan functions, but i can operate 100% with my finger (unlike omnia) views penny-arcade really well and the scroll/trackpad is very useful and responsive. Its like having your own mouse in your phone (better than blackberry's failmouse). App store is small with meh apps, but that will change as the phone becomes more popular. Sounds good, has headphone jack, has SD card slot (inside the battery case, so you have to remove battery every time you change mem cards. Kinda a downer when other phones have easy mem access).
All in all i wish the droid all the luck and hopefully verizon doesn't nerf the phone like they do with their other stuff with that crappy VCast of theirs.
