You haven't even tried the pen? :O I don't use it a great deal. It's handy for the occasional note, screenshots with annotations and navigating menus on some websites. And websites that show animated previews by hovering over a link.

Hopefully CM will be more reliable on the N7000. I have a rather old version still running on my HTC Desire and it's great. My Note 2 is definitely more stable since switching back to a TouchWiz ROM though.
