A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
I use OneNote extensively on my X230T, and have since Windows XP on my old Toshiba M200. OneNote, with ink, is the ONE application that continues to prevent me from migrating to Linux.
Having OneNote on my phone (Galaxy Note) with ink support would be hugely valuable to me. I don't care if it's a paid app or "premium extra" or whatever. I'd even leave the whole Android phone ecosystem for a Nokia Windows phone, if they ever had the smarts to incorporate a Wacom digitizer which supported ink input in a OneNote app.
Basically, I'm just adding my voice to those calling out for ink input support on phones - preferably Android. Having seen the reaction of envy and surprise in my iOS- and MacOS-using colleagues when I use ink on my tablets, I can't understand why MS hasn't exploited this massive potential product differentiation. As my (30 000+ employee) employer starts deploying Sharepoint and Office 365, there is a tremendous opportunity for fully Office-compatible mobile apps to displace the iPhones they currently buy and issue.
