Well, yes I think it won't be possible to run games with an on-screen 
virtual gamepad as the iPhone/iPodTouch does.
Do I am wrong?

I do agree, but for me these rotate and resize features imho aren't so 
needed as soon they're cool to see.
Also using a touch-only screen they don't loose their usability: the 
resize, mostly, could be done simply with a scroll, while the rotation 
using the gimp-way (put a placeholder on the rotating fulcrum tapping, 
then use a finger dragging the image...).
I can't find more things that really need a multi-touch screen, since I 
won't paint on it and I neither will do a collaborative work... :P

Then I'd like to know more infos about *tapping* in Neo.
I mean, in my notebooks with Synaptics touchpads I can easily use more 
than a finger to play some useful actions like:
  - Left clik with a finger tapping
  - Middle clik with two fingers tapping
  - Right clik with three fingers tapping
  - Vertical / Horizontal scroll with two fingers sliding [1]

Well, are these features available on GTA02 too?
In fact, if the answer would be "yes", we could easily use the 
multi-fingers tapping/scrolling features to control the phone in a more 
comfortable way (for example allowing "right-clicks" no more 
pressure-time based, or allowing operations on images like the ones I 
mentioned above).

PS: That's so strange (and funny), today exactly few minutes before the 
topic was started I wandered about multi-touching in Neo and how it was 
used in iPhone, reading and looking much of resources... :P
