It is interesting to note that when the inventors of Swype went to Apple, they were interested, however they declined after they heard it was being offered to other companies with different operating systems.
I have developed on-and-off the Apple platform ~ 20 years, and their Not Invented Here (NIH) reputation is legendary and well earned.
Bert, I know that you are a fast typist, but for your average user, imagine a 10 inch tablet with Swype (and a larger screen so that you could see the letters) as a work tool, that could be what the iPad isn't.
