If you had ever used Swype on Android (it was only briefly on iOS, and wasn't as good as the Android version yet), you would understand how good keyboards could be 10-12 years ago. Perfect precise cursor placement. Cut, copy, paste, and select shortcuts. It was not perfect, but it was rapidly getting there.

Microsoft bought and killed it without, apparently, learning from it. Maybe there was a good reason why, but I've never seen one.
