A serious question: what is the advantage of thinness for you, personally? I have several laptops and I'm on the move all the time. The only disadvantage of thicker ones for me is weight - but it's negligible, even when I'm cycling and my laptop is in my backpack (or, sometimes, laptop bag). Weight aside, the thinness itself has zero advantage for me. I'd much rather have all the functionality removed at the cost of it (not just Ethernet - I care much more about user-replaceable SSDs and RAM).
