OneNote seems to be a widely used, versatile application with plays into both education and enterprise. A hardware device such as a small tablet designed specifically for OneNote could be good foundation for Microsoft to work its way into the mobile(ish) market.
I personally use OneNote for project management and reports and would love a small device (but larger than my phone) I could use in the field – A Surface Notebook.
Just me or could anyone make use of such a device?
