Is standalone really a word?
3Com Ergo Audrey (2000-2001)
Named for Audrey Hepburn, the 3Com Ergo Audrey was an Internet appliance that made its debut in October 2000. According to Wikipedia, it could access the Internet, send and receive e-mail, play audio and video, and synchronize with up to two Palm OS-based devices. Planned to be the first in a long line of Ergo devices, the product was discontinued in the middle of the dot-com bust in June 2001.
The standalone DVD recorder (1999-?)
A lot of people thought the standalone DVD recorder was the second coming of the VCR, but it didn't turn out that way. The DVD recorder was never that user-friendly, and digital DVRs from cable and satellite companies (along with Tivo) made them less compelling. Also, the real DVD-burning action was taking place in the computer room, not the living room. That's still the case today, as the standalone DVD recorder market has dried up in the U.S.
