Sort of off topic on the twirling, but still on the browser UI.. it seems a lot of video reviewers get confused about scrolling and selection.

(Not that I've had my hands on an N900, but .., ) the selection method does seem a bit clunky. I was wondering whether using shift-drag (holding shift on the kb, and dragging stylus or finger) would be a possible alternative..

But then I saw the discussion on a thread about the Q3 demo, mentioning the proximity sensor being used as a fire button, and I got to thinking how useful it might be to use proximity as a modifier (like shift or control) to enhance the touchscreen UI - since I guess you can use it without the kb being out. So that, for example, proximity + drag could be used to select text, and so on.

I don't know how easily this could be implemented, but I think it has a lot of potential for enhancing the interface, and not just in the browser.
