Philips excelled in the design of CD-i by offering various implementations of CD-i in other electronic equipment, like this stereo set or a television (21TCDi30). I think it's pretty unique to find a games/multimedia-console in a stereo set neatly integrated as it is in the FW380i. Philips also offered the stand alone version of the stereo hi-fi set around 1995 and the FW380i was an upgraded version now including the CD-i player with integrated Digital Video capabilities.
Out of all the Philips CD-i players around, these integrated players you come across the least, I can imagine the television may be broken by now or replaced by flat-tv's. Perhaps the stereo-sets are all replaced by surround DVD systems which is basically following out of the idea of the FW380i. CD-i was meant to play both audio cd and video cd which is why consumers often connect their CD-i player to their stereo set and TV anyway. The downside is that once you replace your stereo or TV, the CD-i is going down with it too, and it's a bigger package to save in the basement if you want to. The idea to implement a CD-i in a television was done first by the B&O CD-i system, which you can read more about here. The stereo hi-fi set is, as far as i know, the only version of a console built in a stereo hi-fi set. It included the amplifier, FM/AM receiver, two cassette decks and ofcourse the CD-i player was also the audio cd player of the set.
Also interestingly CD-i Fan found that the 21TCDI30 is a CD-i 210/40 inside a TV! Probably the FW380i is also a known CD-i player version but it is yet unknown to me what type it actually is. If you want to have a closer look on the inside, go to this article.
