Your "except" is pretty big to be put in "except".

Apart from that, simply resistance from users, who are not really "computer people" and basically know that clicking the "w" icon launches the application on which letters can be drafted, is not a small matter. I hope the training programmes are well planned to cover that aspect.

Resistance to change from non "computer people", as you put it, has nothing to do with something Microsoft can do. And concerning the bribery, yes, I wouldn't be surprised if it was one of the main reason linux and free software in general didn't get more adoption.
