Just for the record. In our company we manufacture control systems for 
automatic machines, and we provide a touch-screen industrial computer, 
for easy operator interaction.

In the operating instructions we write:

"If you have difficulties with touch screen, please touch anywhere on 
the screen and watch the cursor position, If it happens not to be 
exactly at the location you touched, please perform the touch screen 
calibration procedure explained below"

Of course we're not using Windows, but rather Linux for a lot of 
reasons, the main one being that we need real-time responsiveness. 
However this one adds one more reason to the list.

To be honest I must admit that industrial grade touch screens have 
dramatically improved during the years, and nowadays the recalibration 
is seldom required, nonetheless...
