I think this would be excellent for spreadsheeting, what about you?
Imagine being able to swap 2 cell contents in one move (without some code/add-in)?
Pinching and stretching to grab selections or zoom?
Transpose with just a pivoting drag?
I already find I’m often using 3 or 4 inputs at once (mouse scroll, left and right buttons and control springs to mind) doing that on screen would be class I reckon.
Perhaps it could also respond to flicking the vees by closing, don’t save changes.
I haven’t (knowingly) tried any multi touch devices (and it appears Apple may have some issues with their new multi touch scroll pad) but I think the theory sounds very promising.
What do you think?
[obviously a 3d hologram thing as in Minority Report would be even more appealing but I can live with waiting for Windows 8 for that]
