I've seen a couple of posts in the past about non-tablet users using digital
pens.

I haven't bought one yet but the portability of the Zpen from Dane-elec or
Iogear's digital scribe seem attractive. They are a small clip device you
attach to the top of a page which record penstrokes. The clip then plugs
into the USB port and you can upload your pages and it comes with handwriting
software. A big plus is that the pen looks like a regular pen, some other
digital pens look like cigars.

Has anyone successfully used either of these with OneNote? How integrated
is the process of getting the notes off the device
