Very interesting

I would love to see this in liqbase......

I was watching a lot of the videos of people playing with the N900. There is a propensity to flick upwards with the back of the finger nail, as well as to use the tip of the finger. This would be impossible on a capacitive display.

What you have highlighted would also be a problem on capacitive, and I think that multi-touch by varying the size of the touch area has a lot of possibilities.

eg finger point moves a Window, back of the finger nail flicks it away and closes the Window. This to me is quite intuitive, having grown up playing with marbles
