Yes, I agree. I've only played with one (an early one) once, and it
was impressive.
Kinda tough to do DECnet with one of those, though. ;)

The wizchip toys are better...all the TCP/IP stack is inside the

You'd still have to come up with driver support for each classic
platform you wanted to support, but that's the same no matter where
you go.
Even easier is the ENC28J60 from Microchip. It's even available in
DIP form, for the SMT-phobics. It interfaces via SPI, which is trivial
(but slow) to bit-bang on most any processor. I've used it a few times,
it's quite good.
