Bill was too early, didn't want to do the necessary UI work, and didn't have the hardware team to push the hardware standards up. I remember people trying to use windows tablets. They were full-on laptops running an extended version of windows, with a few apps and a handwriting recognizer slapped on top. They were heavy, confusing to use, and not terribly finger-friendly. They've got good reason to stay out of this one. iOS came from Apple's phone OS (esp. in terms of UI). Until Windows Mobile starts getting some traction, MS is better off staying out of the fight. You can always commoditize your opponent later.
