This is one of the coolest products I have seen in a while.

It records your notes electronically and has a microphone to also capture your meeting or professor as an mp3 file. It can then read your notes back to you as it highlights the text on your computer.
It is amazing great for meetings and for college kids or education in general.
FYI- I have no affiliation with this product at all. I just had the pleasure of testing one a week ago and it was amazing.
