Yeah... The Wii U really should have had an Ethernet port. I don't really get why Nintendo decided to do Wifi only with the Wii and Wii U. I've been thinking about getting a Ethernet adapter, but I'm going to wait for more online multiplayer games first.
I've been playing the heck out of Nintendo Land since it's my only game. I'm still waiting on New Super Mario Bros U and Assassin's Creed III from Newegg. I really like the Donkey Kong game and the ninja game.
