My brother in law, who is a foreman for a crew of painters on Disney property, has been waiting for this, specifically for office. I've often suggested that he could just collaborate on documents (and they do this often) through google docs ... but office/windows is entrenched, and he'd love it if he had access to office on a tablet.

"That's it" is in the context "(people) want to run Windows software on it". Existing, Win32 desktop software that people are used to.

This part is not going to happen.

And sorry, office on tablet is not a big deal. You will understand, when you will have to use it. It is the same reason, why PC tablets were not successful - the usability is way worse than existing solution.
