Sort of like saying why haven't we changed from RJ-48's for phones...old habits die hard I guess! For the most part the RJ-45 connector is pretty sturdy...remember those silly dongle cables that were used for pc-card Ethernet adapters in laptops...those things would last about a month before dying! As for the Raspiberry PI (I own one) it was silly to even put Ethernet on that instead of wi-fi, especially for the educational market that the PI was initially developed for; what classroom has Ethernet running to every desk especially in poor nations where copper theft is rampart!

I was looking at a Raspberry Pi board and was struck with how large the ethernet connector is in comparison to the board as a whole. It strikes me: ethernet connectors haven't changed that I'm aware in pretty much 25 years. Every other cable has changed several times in that time frame. I imaging that if anybody cared, ethernet cables could be many times smaller. Looking at wiring closets, etc, it seems like it might be a big win for density too.
So why, oh why, nanog the omniscient do we still use rj45's?

Seen an AUI or vampire tap recently? Vampires made a certain amount of sense, but the AUI connector seemed to have little purpose other than recycling weak metal from Coors beer cans. IIRC, the inventor apologized.
