You can type or hand write as well as sketch drawings in
OneNote. With OneNote, you can enter typed and handwritten notes
and other information with a keyboard or an inking device such
as a mouse, a Tablet PC, or a graphics tablet. If you use a
Tablet PC, handwritten notes can be converted into text
(handwriting recognition). If you're using OneNote on a desktop
or laptop, you can still use an inking device, or simply, "ink,"
for writing or drawing, but handwriting recognition is not
available. Also, keep in mind that hand writing with a mouse is
very difficult and is not recommended. As with paper, you can
write (or type) anywhere on a OneNote page. Just click and
write. The inking technology is really great if you'd like to
include sketches or diagrams; you can doodle away as you would
on paper.
