I could have just done a +1 on this, but felt a post would be more impactful. I too bought the Surface and love it for notetaking. Am still a loyal Evernote user and have been for years, but OneNote is really calling me now .... it lacks a few things that Evernote does nicely like snagging screen caps but MSFT is enhancing OneNote quickly.
Everyone I know who has the Surface focuses on how great drawing and handwriting in OneNote is.
Evernote product mgt - take heed!! Time is growing short.....
(Ps: I've yet to switch out of Evernote Touch on Surface to Evernote Windows. I do hope that doesn't accelerate my move to OneNote... just saw the notification of deprecation)
