Nice thing is that the desktop app can sync/save copies locally and does private backups, but you can also save/sync and store data in OneDrive, private server, or corporate internet via a samaba share (Free version only syncs to OneDrive, but IIRC does local backup in desktop app). Architecturally it's a very impressive product and makes some pretty creative uses of the windows folder hierarchy to get it's job done.…
What is inking support?
However, although it's amazing compared to a pen and paper it's still incredibly frustrating to work with.
* It can't handle large amounts of handwriting without igniting relatively powerful computers
* It crashes constantly when trying to balance pen input with palm rejection
* Syncing doesn't really work with non-trivial merging and doesn't handle sync errors nor errors in general well -- all of these usually end up with handwriting layered on top of itself
* Syncing is basically out of your control, you can't do partial syncs when you really need a section/page fast, and large notebooks with handwriting can take hours to sync completely. I've basically resigned to splitting my notes into many smaller notebooks.
* Handwriting on the "Desktop" version is a complete joke and so you're constantly switching between the that and the app to get good handwriting and more features.
So it's great, until it doesn't work then it's a nightmare.
