Having done a lot of searching in these forums, there seems to be a general unbelief amongst 'the powers that be' that this problem actually occurs. Almost as though their thought is "ahh, that sounds like weird stuff, must be user error or the guy doesn't understand how to use a stylus or doesn't know that there's a recalibration tool".

Well, we're not all clueless dolts - it's a real problem and the recal tool makes it worse not better.

And the effect on usability is dire.

Please somebody pay us some attention !

Reflashing doesn't help. Removing battery doesn't help. Recalibration certainly doesn't help.

There's no way I can let anyone else use my N800 because they don't have the "displacement map" in their head of where they need to touch versus where they want the touch to register.

If there's one thing that would help the N800 get more popular, it's letting other people use them. But for everyone with this screen problem, if anyone does try to use their N800 they'll find it a frustrating and pointless exercise. What a very great pity.
