Updated: now as I have installed USBMouse it is fun to watch
the on-screen cursor following my messed-up touchscreen.

I have searched for and not found "USBMouse", could you please mention a source !
It seems a nice way to check my screen regularly.

Re: Touchscreen calibration.

I am wondering how durable the screen is.

In another thread some members have told how they carry their IT in a pocket.
( I have myself damaged two screens in my pant´s side pocket. 1) A handera PDA, the lid was not stiff enough and the screen got burned from behind if pushed inwards the slightest. 2) A pocket camera screen, although it had a stiff protection. )

>> Could to much occasional squeezing of the screen influence it enough to change the calibration, or even make the screen response nonlinear ?

And: The screen calibration in the N810 with only 4 corner points presumes a linear screen.
Some of the described screen resonse problems would need 5 (or 9) points to calibrate a more or less nonlinear screen !

( My own N810 screen: After a few momths of use the stylus response was about 2 mm off, restored by recalibration. )
