Also, over the past few weeks I cleaned up an old Model M I found lying around in college, and pressed it back into use with one the computers that one of the college societies I'm a member of has. There was something rather satisfying about it that distinguised it from the Model F so I decided to get one. It was either a Black M13 or an Industrial, and I felt the M13 was better value for money because of it's Trackpoint.
