Ah...I was just at the Apple Store. I wasn't able to try out the handwriting recognition because they didn't have an app on the demo units that used it, but I was told third-party apps do have handwriting recognition.
I also tried the Smart Keyboard on the 9.7 iPad Pro. Guess what? I like it. I'm sorry to say, but if I end up getting the iPad Pro 9.7 and I don't see the TB shipping, I'm going with the Smart Keyboard. That keyboard is not bad at all, and I can see myself typing long documents on it.
I'm sure the TB is more versatile because it can be used with other devices whereas the Smart Keyboard is only for the iPad Pro 9.7 inch (if I buy that one, that is).
