I agree and by the time I replied to this you had 29 votes of approval, the largest number I have personally seen. I don't use Ethernet every day, but when I do it is typically without much notice and with intense need. What if I don't have my dongle that day? If I need Ethernet, and as near as I can tell I will need it for at least 2-3 more years (need), it should be a default feature. The case is tall enough for it, the plug would simply have to go down into the lower bevel a bit.To be honest is losing something as vital as an Ethernet port worth those extra millimetres shaved off?
I used to use Ethernet every day on the Mac I currently have so it is not some distant memory.
There needs to be some ultra compact pocket/coin size dongle to resolve this omission.
I get there is faster wifi in the device, but is it on the other end? Not always. I get there is TB and and USB3 that is great. Ethernet is literally a technology developed at Xerox-PARC and is still totally pervasive to this day. And a security feature too.
