Olympus DM-1 Digital Voice Recorder - PAGE 1
Patrick Woo - Monday, October 1st, 2001
Introduction
Unlike most other units, the Olympus DM-1 digital voice recorder and music player is actually targeted at corporate consumers, moving away from the already densely populated mainstream MP3 market. It is touted as a voice recorder, first, setting its sights at dictation oriented consumers. In second is the DM-1s music player functionality, supporting both MP3 and WMA. Nonetheless, it performs both functions at such a high level that it will likely lure away many mainstream consumers.
