Well, I don't have any hands-on experience with OS2008 yet, but all the pictures I've seen looks ugly to me, compared to OS2007. It looks childish toyish, and everything is huge, which is probably to make it 'finger friendly', which I don't care for at all. The stylus/finger detection mechanism in OS2007 works well for those few situations where a larger click area is welcome. The changes I want for the UI in OS2007 are all about getting _more_ information into the display, not less.
