The professional version has the following extra features not found in the free version: Mixed language input, different layouts, enhanced mistyping correction, context based prediction and correction, dynamic layout resizing, "my sentences" ability, "my commands" ability, customizable emotion icons. Of all of these features, the "my sentences" and content based prediction and correction are the most valuable to me.

The app is fantastic, and it's a good price at $12.98. I bought it a couple of days ago for the extra features and to support the developers.

I was using a keyboard on the Centro before switching to the diamond, and after a week with Touchpal my input speed on both devices is now about the same.

Touchpal has helped convince me to stay with the Diamond and not get the Touch Pro.
