Just like darkknight22, I type faster than I write. Regardless, I believe that I would purchase one of these pens. I originally wanted a tablet, but I found that they have some limitations when looking at regular pen and paper. While this device is a little gimmicky, I feel that this would help me immensely.
It is a little difficult typing everything that my professors say, but some people get a little bitchy listening to "tap, tap, tap" all during class. Of course, I could not care less, but I would rather be able to take notes and refer to what the professor was saying when I took a particular note.
While I believe the pen is not too overly priced, the paper seems to be a little high. If they would sell the 2 GB pen for USD$79.99 and the 4 GB pen for USD$99.99 for students and set the notebooks at $5.99 for two or three, with each having 100 pages, then I would be all over the product for sure.
Have you ever tried cramming all the notes from a majors class in 80 pages? I know that I cannot do that. My Organic Chemistry class took over 200 pages of small print to get my notes covered.
Since I do not own the pen, I do not know all the features on the pen. One thing I would like to see on the pen, if it is does not have it, audio out port. Since listening to the menu options in a lecture would be a big problem(sans an audio jack), this would be a rather large issue.
Another issue I wonder about is the quality of the microphone. I have been in some large classrooms and I have not found a good quality audio recorder that will get everything the professor is lecturing about. I have had to get directional microphones to make sure that everything told to us(students) is picked up by my recorder.
