In the new calibration procedure, you have to press the three calibration points twice in succession, with each try being within a small error factor of the previous. You might accidentally miss a button once, but not twice, and certainly not twice the same way. If you show me the specs, we can probably even throw out "that can't be right" calibration input from users.
Take a look at a palm pilot some day. It doesn't have a keyboard. It does have touch screen calibration.

> > Keyboard navigation probably makes some sense for the administrative functions: tab through buttons, space to press button, etc. But before we get in a knot about this, just how far out of calibration can these things really get on their own before we just declare the touch screen broken? I mean, its a big button, and you can always use some smarts and touch a little to the left or right based on feedback. If the screen is going out of calibration to the point that this technique doesn't work, something is seriously wrong.
