I also am learning to use OneNote. I am not comfortable enough to take notes in a meeting yet but am getting there.
I tried to get used to OneNote but never got anywhere near comfortable enough to take notes in a meeting with the Wacom pen on the SurPro. I've had MUCH better luck with Evernote and using my phone to scan hand-written notes. I considered buying the Evernote Moleskine, but grabbed around a dozen 6x8 notebooks at a trade show with a light grid pattern and some pretty industry-appropriate pictures scattered throughout. With Evernote Pro, the handwriting recognition has been extremely/surprisingly ccurate even with my near-physician chicken-scratch.
