Seriously, any url about it would be an interesting read.

I am thinking that it would be mostly useful for marketing/fanboy argumentation. Much like the whole "resistive screen, what is this, 1999?" thing.
However, I don't think the zoom circle solution on the N900 is optimal because it drags the page around at first. A pinch or dedicated space like on the HTCs is more accurate. I am sure that some people will like an alternative to the zoom circle. So a good solution on this may just become popular.

I may look for it, but in principle on the resistive screens the point is the average between two points of contact:
you put one finger in X, you save the position
you put second finger in Y, for the device the point of contact will move rapidly to (Y-X)/2
by moving your second finger you change the second position relatively to the first one
I hope you understand what I mean
If not, I will try to search for any video demo, as I know it exists. You can always try this on your resistive touch device (if you have any) in you drawing program.

I believe a similar effect can be seen in a tabletPC / wacom tablet (if you have two pointing devices) and it's behaviour sounds sort of like how the touchpad acts too. Although a touchpad is relative positioning.

Yes, that's where the fun starts
I believe, it should work quite well, a nice little trick...

I will be soon looking for a topic for a small project, so I was wondering, if you think that there is really some use for zoom in/out and rotate gesture that use two fingers? It would work similarly as on iPhone (only one finger needs to stay in place and only would move).
Would you use it on N900? Do you think it is worth spending some time on it (besides obvious fun of doing it
Thanks for your opinions.
