You said, "However just using a conventional type Monitor as a Touch Screen in a Desktop for business is going to fail the Occupational Health & Safety Test every time."

I agree. Using a touch screen monitor in the conventional 90 degree angle with respect to the desktop could put a strain a user's arms and shoulders.
BUT
A touch screen monitor should inspire us to use it in new ways. Maybe the conventional orientation is wrong for a touch screen.
Using a touch screen monitor closer to the keyboard and at a 30 - 40 degree angle with respect to the desktop would be quite confortable. I also think it would also be easier to use for people who are not touch typists as the monitor would be much closer to the keyboard and at a more complementary angle.
For example: The Acer T232HL is a ten point touch screen monitor that can be adjusted to 178 degrees.
If it only accepted stylus input. (sigh)
