why haven't ethernet connectors changed?

I have noticed that too.  However it is not the RJ-45 connector's fault.
It is the morons that insist on recessing connectors in places where you
can't get your finger on the tab.  I like the patch cords that have the
kind of loop/spring thing for a tab that does not catch on everything
and that way you don't need the boot over the tab.  Another pet peeve of
mine is connector boots that harden up over time so it is nearly
impossible to flex the tab to remove the cable.  Also, how about the 48
port 6500 blades and trying to remove the cables near the blade
extraction tabs.  Grrrr.

The only thing I would change about RJ-45 is a longer tab (but make it
optional) for when you care more about ease of removal than cable
tangles.   Polycom phones are hell to try and unplug the RJ-45, for
example.

Please, no connectors that do not lock into place.  Is plugging in the
RJ-45 that much of a task?  Most portable devices are going wireless in
any case so they are not an issue.  The RJ-45 has worked OK for me.  The
AUI connectors have a special place in networking hell.  What an
incredibly horrible mechanical design they were?  The flip side of the
question is why you think the RJ-45 should change.  You could argue that
you don't usually need all eight wires but every time we tried that
argument someone came up with a compelling reason to use more wires.  I
like that it is very standard.  In the fiber world it is a continuous
issue of hybrid patch cords dealing with ST,SC,LC and all the other
variants out there.  It would be a huge nightmare if the same thing
happened with copper Ethernet.

I am also not a huge fan of the USB connector because I have seen a lot
of those break and there is no positive retention.  Magnetic is cute but
has no place in a datacenter and even with desktops I can picture a lot
of support calls because someone bumps a wire that knocks the mag
connector out of place.  I really hate dongles of all types but I guess
you don't really have a choice with devices so physically thin that you
can't get the jack in there.

I think I will keep the RJ for now.

15-pin D-type AUI connectors with slide latches?

BNC for thinwire?

I do agree though, something more like mini-USB would be more
appropriate for home Ethernet use.
