More impression about iPad 2 from me:
Sound:
Similar to what runawayprisoner has described, it does have more cooler signature. The setting for setting, the treble department is more live. It also sounds more "spacious" than the sound generated from iPod/iPhone 4 gen devices. I really like this spacious sound as well as the slightly increased echo sound.
Back to Video quality:
Due to the lack of contrast video setting for playback, it doesn't have as much depth as I would like it to be. But still, the video displayed on the iPad 2 is very impressive. They look smooth and yet still bit sharp. There is no color bending of any sort. It's smooth as butter. The trick for me was to lower the brightness setting anywhere from 20~ 25%. 50% was just too excessive, for any indoor lighting conditions. Brightness at 50% or more introduced a bit of picture grain and noise, and also hurt black levels, such as dark scenes in the video and the black bars top and bottom of the screen.
Physical Characteristics:
I find its design beautiful. I do like the fact that the top side is entirely covered with glass. White bezel, which I'm glad I got, also sits underneath the glass.
Weight:
It's too heavy. :| Before I got the device I was expecting about one half of the weight. Maybe I was expecting too much? I guess that glass and battery is taking up most of the weight.
Nevertheless, cheez loves iPad 2 a lot.
