So you don't buy into the argument that vertical touch screens are unergonomic and unpleasant to use over non-trivial amounts of time, because they require holding the hand up to the screen?
I think we're in the same state we were in a month before the iPad shipped. Will we really like a giant sized iPhone (as it was positioned at the time)? No one really knew. I think it's fair to say that it was mischaracterized, and people really do like it.
Interestingly, even the Verge (who typically skew anti-MS, but fairly even) seem to really like the experience thus far (with some reservations).
Ask me this question in a month or two after I get some actual touch screens. :-)
But when a laptop or a tablet is being used, a touch is very natural because the screen is at the right distance and more importantly at a "right" angle. In fact it is way more convenient to use a touch based laptop instead of a tablet because of the angle the screen is at and the arm rest that the keyboard provides. Try it out yourself. I have RC running on my old hp and it is pleasant to use
