In 2009, I did the same search. Back then, HP was still making table PCs. A stylus-based tablet PC with onenote is a really good system for taking notes. It makes your handwriting searchable and it handles diagrams more cleanly than any regular laptop solution.
Now, with tablet PCs on the way out--HP doesn't even make them, last I checked--you could try a galaxy note, or the Eee Slate, though both of those options leave you without a keyboard.
