A new way to touch type because of the iPad

As a touch typist, I am rather picky about keyboards and input methods. I always liked the mechanical keyboards with the old “Cherry electronics” keys. After switching to the Mac, the only reasonable keyboard to use is their aluminum external keyboards (wired or bluetooth model), but is is far from ideal.

With the iPad coming in a month, touch typing with reasonable speed is going to be doable if you are typing on the iPad in landscape mode. Now we are talking about touch touch typing — without any mechanical feedback. Will it work? Is it better ergonomically? Any physiology doctorate students want to take this on?
