I think imve posted on this thread already but thought of a couple of other minor niggling issues:

In the phone and messaging apps, when you scroll down through calls/messages the 'new call/message' and 'select contact' buttons also scroll up and out of view, so if the person you wanted to call isn't in your recent calls as you expected then you have to scroll back up to select them from the contact list. only a small issues, but annoying..

Also, the notes app doesn't support kinetic scrolling, only a fiddly scrollbar.. Then again, that does mean you can highlight text easily..
