I am impressed with the sound quality of these digital recorders. Easy to keep lectures seperately in folders and download to laptop. It comes with digital voice editor software and has playback speed controls so I can type the notes. I can easily email the notes to all my fellow students who missed a lecture both the voice data as an MP3 file and the notes I typed. It is compatiable with Dragon Naturally Speaking Software that will automatically transform my voice data into text. When you buy from Sony it is included with the recorder. Wonderful for a psychology student or a therapist.
