RCA RTD750

Built-in 20GB hard drive; TV-based media navigation; plays Internet radio; displays album artwork and music information; compatible with broadband and dial-up connections; can transfer tracks directly to some RCA MP3 players.

Lackluster sonics; can't stream media from networked PCs; can't play video or image files; no progressive-scan video output; no coaxial digital-audio input.

The first networkable HTIB with a built-in hard drive, the RTD750 is a harbinger of convergence, but it has significant shortcomings.
