Just because you don't like it doesn't mean it's not generally accepted. When was the last time a MacBook had one? And they still sell like hotcakes. Ultrabooks are selling pretty well too, without Ethernet. Even the Dell XPS that everyone recommends doesn't have Ethernet.

It's generally accepted that Ethernet is gone now because people have been buying laptops without Ethernet for years now.

Is that because they are selling laptops without Ethernet? We may be confusing the effect with the cause.
