Apart from their Spinn 70s-retro analog goodness, iRiver had two beautiful concept products in their IFA 2008 stand which had a design that looked further into the past, as far as the beginning of the 20th century. As you can see in the video, both their Clix speaker-inspired by the shape of cathode ray tubes-and their pipe music player-which you can blow to mute (insert joke here), and connect it to a speaker resembling a phonograph horn-look both intriguing and beautiful.

I dunno about these concepts.
The Spinn brings to the table an interesting twist on a common UI paradigm (that is to say, a moving or spinning mechanism to navigate some sort of menu), and does so with reasonable success and a nice retro flair.
These concepts, though... well, I just can't see them being at all practical.
