If you (for some reason) have been longing to draw on your SP without actually touching the screen with your pen try this. Hold a piece of cotton cloth (like a t-shirt) over the tip of your pen then hold the pen about 3/4 of an inch from the screen. You will see that instead of the cursor appearing the pen actually writes. Don't ask me why. I stumbled upon this when I was wondering if someone could design a felt nib for the end of the pen to have a more marker like feel and i wrapped my t-shirt over the pen tip. This works in OneNote, don't know about elsewhere.
