Serious question:

Aside from school note taking and small meetings, is there any other purpose to this?

I'm trying to think of another scenario this would be useful.

It would be cool if this could do some basic Visio diagrams or something (even though I haven't used Visio in years).

This seems so darn cool, but I barely write anything by hand anymore. Just some basic design (layout, diagrams) and lists (groceries, supplies, to-do's, etc).
