Hmm, yet there are millions of keyboards available for them.

That's true of all touch interfaces.

Much more mobility.

In pretty much every case now.

The UI would need to be reconceived. Which it should, since touch screen 
is a different way of interacting with software. But I'd think a 
properly-structured application has the UI and backend components 
properly separated. So the same backend can be controlled via different 
front ends.
