Does anyone know if it learns from your writing style to make its suggestions?
It doesn't look like it--it keeps suggesting phrases with exclamation points, which I dislike and never use. I was prepared to hate it at once and turn it off, but I decided to try it for a while. I haven't quite decided whether it's saving me any time or not, but at least I have learned to dismiss it quickly when I care to. I can see how I would have liked it for routine business email.
