Nah, it doesn't work like that. You couldn't search hand written notes.

I've never tried it but I think the OCR stuff happens remotely and the only output is email. As in, you can email yourself a notebook and it will arrive as text. The whole idea of this seemed so clunky to me it could barely be called a feature.

Similarly with services like onedrive. I think you can upload a notebook to onedrive but not sync with onedrive.

This may have changed, I haven't looked into this for a long time.

My advice would be to think of the device as a paper notepad with infinite pages, nothing more. If that's not worth it for you then don't get one.
