None of the USB nor firewire standards provide for positive retention. eSATA
does sort of in some variants but the connectors for USB are especially
delicate and easy to break off and destroy. There's the size of the Cat5/5e/6
cable to be considered too.
Then you must consider that the standard must allow for local termination, the
RJ45 (And it's relatives) are pretty good at this. Fast, reliable, repeatable
termination with a single simple tool that requires only a little bit of
mechanical input from the user of the tool.
If you look at the Raspberry Pi though, it takes a substantial piece of real
estate
though. Not everything needs to be industrial strength connectors as witnessed
by USB and HDMI -- if they fail I'm just as unhappy as if ethernet fails.
Surely we
want keep shrinking these cute little purpose built controller-like things and
not
*have* to rely on wireless as the only other space-saving means?
