Some of these are small busineses using it for a limited range of applications.
Again that isn't a fair statement. It implies limited functionality. I can do everything with a mouse pointer that I can do with a swiping finger. Absolutely no functionality is forsaken if you don't have a touch screen.
As for the increased productivity I suppose that's possible to some extent if all you're doing is pressing and whooshing tiles around. But those tiles are only fancy buttons to get to the underlying functionality of an application. For my usage real productivity comes in the form of creating something. That requires a keyboard. try building a full scale...anything...using only touch and whoosh with let's say, on on screen keyboard and two fingers even.
