Basically, they're trying to get more people to use spreadsheets in a non-business way. People already do, but the natural way to grab more users right now, is to put it on a multitouch tablet.

I think stats and a lot of other serious number-crunching/business oriented software is ready for multitouch disruption. I've been toying with the idea of taking an all-in-one HP multitouch pc and turning it into a "workstation surface" mounted horizontally and implementing serious business apps on it.

I'm in part motivated by my girlfriend's RSI. (Non-carpal tunnel!) Touch interfaces and styluses seem to bother her much less. No stats programs let you use it end-to-end that way.
