Could you draw straight lines along the edge zones on the NT...? That's something I'm unable to do on the NC.
I know with the nature of capacitive screens straight lines are just not quite possible, at least with a finger or those styli available on the market. Even then drawing a straight line along the edge of the NC resulted a significantly more jiggled line than the one drew in the middle of the screen.
Perhaps you can use an app like Touch Test on the Market (https://market.android.com/details?i...ouchtest&hl=en
