Daneel, yup, we all have different bodies, so things feel different to us all. However, I only quite recently realized that the vertical feedback isn't really the problem, and that the lateral feedback is much more important to me. You might too, if you dig into it! :-)

The Tactus is very similar to what I am thinking of, however, I think the real estate taken by the keyboard is an important factor too. It might be that the domes of the Tactus are enough to make a portrait keyboard useful so that the lost screen area isn't so big, let's hope!
