Very important update!
I've been fiddling around with some options of the touch panel, and I've found one that is really interesting. Remember that my original plan was to replace the writing tablet I used by the touch screen? And remember I noticed that the touch panel wasn't sensitive enough to write in small handwriting, as I normally do on paper?
Turns out I was wrong! The touch panel is very much sensitive enough, even to the smallest detailed touches. There is this feature in the driver called 'Cursor Stabilization'. What it does is exactly what it sounds like, correcting small and shaky movements to a more streamlined line. But as I wrote an 'e' or an 'a' for example, it interpreted that as a small shake of my hand and replaced it with a straight line up, making it kind of useless to read you might think. But as I turned of this feature (by a simple unchecking the checkbox), the screen is now really sensitive to even the smallest touches.
It is now very much like writing on paper, and by using the shortkeys CTRL+ALT+ARROW I can turn the orientation of the screen upside down, turn the N10 upside down, and be writing as on a real sheet of paper (one a lot smoother!). This is kind of heaven for me, yet another device (the tablet) I can leave at home
Needless to say it also makes the touch screen much more useful for Photoshop-retouching or hand-drawing things, as it now almost pixel-perfectly maps your movements on screen.
Don't make me "touch" you :-D
