I am, but I only type the messages I need to type. Which aren't that many. If there's some long explanation to be had I call or I leave a voice message. And yes, I am aware of the fact that everybody hates voice messages, but it's only fair if somebody requires my immediate attention :).

Typing is painful, but not disastrous actually. It's perfectly serviceable.

I used one for about a year. I thought I'd be using voice-to-text a lot to get around this issue, but couldn't get used to the idea. A swipe-style keyboard does make typing much less onerous that you might imagine though.
