I disagree, strongly. It is precisely as bad as he thinks, and what makes it worse is that it damages the viability of a pen-based workflow (which I am in favor of, because I do a lot of visual stuff and I use OneNote quite a bit).

I want to be able to disable it entirely and not smudge the crap out of a screen I'm trying to work on, but it's effectively impossible and when you do disable it it all falls back to keyboard controls and leaves you with a garbage pen exeprience.
