Nintendo recently granted LaserLemming.com exclusive access to the Wii U Experience in Los Angeles (only several dozen other people were invited). Since I am just about the only regular writer for the site that lives near LA, I grabbed by girlfriend and made my way to LaLa Land.
Several outlets have already given detailed previews of the Wii U Gamepad. So the only reason you could possibly be interested in this preview is because you are an intelligent human being that likes to learn from a variety of sources before making up your mind about something. Congrats on being a critical thinker! On with the bullet-points!
