Not a COMPUTER but I have a Pro-log M900 EPROM burner that has a second source INS4004 on
the board. This isn't my M900 (my INS4004 is white/gold), but here is a view of the
board/chip: http://www.wolfgangrobel.de/programmer/img_m900/m900_06.jpg

Don't know about commercial products. But a classmate of mine got Honors in
Independent Study for a project where he built a useable general purpose computer out of a
4004, plus a boatload of other stuff. It filled a wire-wrap panel board about 8 x 10
inches. He wrote some software for it as well, and took it to a summer internship at one
of the National Labs (in the Midwest -- Argonne?) where as I understand it they liked it
enough to ask him for a copy of the system. He graduated in 1975, so the work was done in
the year or so leading up to that.
One complication was the terminal I/O (Teletype 33); originally he had a bit-banging
interface for that, which isn't easy on a 4004. At some point he finagled a UART chip
out of one of the DEC field service engineers, I think that was one of the first single
chip UARTs, used in the earlier DEC PDP-11 terminal adapters.
