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!
