Strange thread. While it's not that big of a deal, many people do prefer wired over wireless. I know I certainly do, especially for anything I use to stream video.
What surprises me are the people who are getting defensive over the criticism. An Ethernet port would likely have cost Nintendo a few cents per console. It should have been included. I don't get why anyone would be upset over people saying this. It's something they should have done for the convenience of the consumer. Including options is never a bad thing.
A large corporation skimping out over including an Ethernet port on their gaming console is just kind of lame.
