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!
