Even the current solutions are not allowed in classrooms by many professors. Our product is intended specifically to be a professor approved device for those who can not keep up with fast writing.
For example: Press 1 and then record a lecture. You can stop it, rewind etc. That first lecture remains active until it is deselected by pressing it again. (The button will be down when selected and up when not in use). When you upload the files to the computer, a pop menu will allow you to choose to upload all 4 lectures or just the ones you choose.
