I heartily agree with everyone who has expressed concern about the username, userinfo, avatar, etc., being displayed on the right side of the page rather than the left side. It would be really, really great if this could be switched back to the left side.
I don't really have any problem with the new skin, at least as far as the color scheme is concerned, but I am having a hard time getting accustomed to the new icons. As others have said, they just aren't as visually distinct as the old ones.
I'm not a huge fan of the new font, either. The old font -- Verdana -- was very, very easy to read, even at small text sizes. The new font -- Trebuchet -- is relatively easy to read, but it is more narrow than Verdana, and just doesn't have the excellent readability at all sizes that Verdana has. Trebuchet is a prettier font but Verdana wins when it comes to readability.
Overall, I am getting used to the new software and the new features, and I'm sure that most of it will become comfortable and familiar very soon. The increase in speed and reliability (which is thanks to new hardware, I assume?) is very nice indeed!
