What's the rationale behind this story then? A VCR is a pretty one-sided
story. Most CD players, tuners, receivers, amplifiers and TV's are built
using off the shelf parts. Anyway, except for the mechanism, most things in
a VCR could probably be built using conventional parts. And when you
purchase those parts in large quantities, I'm sure the price would be
comparable, maybe slightly more.

Anyway, the morale of my story is that most consumer electronics will in the
future be based on generic parts such as MCU's and DSP's with very few
custom parts (programmable logic such as PLD's could still be used but these
are also COTS parts). And more and more appliciances will use SoC
(system-on-a-chip) parts where most of the functionality will be wrought by
Referring to your Walkman example. I could design a ARM based MP3 player
which, by reprogramming it, could suddenly play Ogg Vorbis files or even
MP3Pro, AAC and MP4 files. I see real value in this. People could add
software which alters the standard playback behavior by adding playlists or
something (would probably depend on the device having a flexible user
