All this beating up on the 8051. They are actually a fairly capable chip. We used them
quite extensively in my work.

that's kinda the point. ;) As I understand it, the very first
prototype implementations were discrete-chip 8051s, but probably of
some more modern incarnation, and that basic design hasn't had any
reason to change.
To some extent, that may still be true for the devices themselves.
I've still got a bunch of USB peripherals with Intel N82930A3 chips
on them, which, I believe is nothing more than a specially-configured
8051.
