Actually, I agree with you 100%.  I was referring to a "Walkman" as in a cassette tape device, not a CD player.  And, most of the stuff on
Napster is NOT being encoded with Fraunhoffer's stuff.  (Every time I've tried L3ENC, it says it's expired.  Anyway, it's obsolete.)  Most
folks are using stuff derived from free source code versions of several encoders.

If I recall correctly, a 128-bit encoding gives about a 50-60% reduction over the equivalent WAV file size, which is STILL a large file.
Higher encoding rates yield larger files.  These are difficult to manage over 28.8 or 56k modems.  (I read somewhere that over 50% of Napster
users are not in the USA, and their access is limited to dial-up modems.)

  Mee too!!!  Actually, I've seen four or five of them on the market.  Unfortunately, they're still in the $200 range.  I'd say in about six
months we'll see them for around $100.  Some chip mfgrs announcements indicate that just about every new portable CD recorder being designed
today will have an MP3 decoder chip built-in, so we'll see 'em on sale for next Xmas.
