Chen,
There is no such problem.
Again, look at http://www.positivesystems.com/tps121v.htm
These PCs work very well, given that the right application is there.

It's ridiculuos to talk about driving a browser, designed for to be
controlled by a mouse, with the coarse resolution of a finger.
But computers are not used onlyfor to run Word and Firefox.

There are circumstances, like for example a restaurant in the center
of an expensive city, where these PCs have fit. One of the advantages
is that they need no keyboard, no mouse: this reduces the space the
computer needs, leaving more space for tables.
Also, operation is fast, just point and presto!. Also, no need for
additional light.

These computers are not experimental. They are working since years ago
specially in Europe.
Finger smudge has no influence on their behaviour, as the sensor is
capacitiva and reacts to pressure, not to what it sees.

As of the postural problem yes, it's a pain to operate a touch screen
IF the monitor is on the computer, at your face's height.
This is not the case. These PCs have the panel mounted in the front
and it gets located more or less in the same position you'd have a
regular keyboard, or a copybook if you were writing with a pencil. The
user can set the touch screen position where it's more comfortable.
Aches and pains are not worse than for regular PCs, maybe easier.

All this discussion stems from thinking of operating the same programs
on the same PC layout, which is not the case.
Even Han is demonstrating different applications in his video, and the
position of his arms does not seem tiring, being the panel position
similar as that of a traditional drawing table.
