I checked out the new IPad 2 today. I have the first iPad and the first thing I noticed was that the iPad 2 was noticeably lighter. Feels more comfortable to hold.
Build quality was up to Apple's usual good standards. The only disappointment was the camera quality. It was grainy. I didn't get a chance to try out FaceTime or Skype yet. My friend lined up for me and he is passing it to me in a couple of days.
