For me, and for nearly everyone I know, thinness is far more functional than an ethernet port. As is weight, a pound is actually a lot!
Ethernet ports are easy to add as a dongle, you can't do the same with thinness. I really only need ethernet in fixed locations, and where there I already have power, and that's the case for most people.
It's totally cool that you have different needs, but it's not cool to misascribe that to "looks."
For me, the lack of an ethernet port is a dealbreaker, because most of the on-site work I do at clients requires it. The last thing I need is to forget a dongle.
I myself gave up on Apple after my 2011 MBP bricked itself last year.
That was too bad, because I really liked the discontinued unibody form factor. If I was spending money on a new laptop, it wasn't going to be a two year old 2012 unibody or one one of the newer thinner, less user-serviceable models.
