Have been using OneNote 2013 since I got my SP about 5 weeks ago. I bought Office 365 which comes with OneNote 2013. I had been burning through physical notebooks for 25 years, and am thrilled to be able to take notes on my SP. No more physical notebooks and great ability to reference notes by account/subject/date. I don't use handwriting recognition, just lots of chicken scratch notes, with a lot of subpages per account (I'm in IT consulting sales). I just noticed that OneNote MX is the same thing but a Windows 8 app? It's not called OneNote MX anymore, just OneNote. Not sure I understand. OneNote (MX) has very cool pen recognition called radius (I think) but now I have two icons on my Win 8 "metro" desktop. OneNote I understand one of them is a Win 8 app, but isn't Office 365 a Windows (8) application? Should I just delete OneNote 2013 and use OneNote? Thoughts? Thanks very much, I would guess I'm not the only one with this question.
