Update: After this was shot, Sphero released an update to their app that adds the option to skip the leveling up business and remove shields from the app. It's possible that this would make this a much better product than this review indicates, but we haven't tested it with the updated apps yet.
Remember the Sphero? It was a smartphone-controlled ball that you could send zipping around your house and drive your pets crazy. The second generation Sphero was just released, and Will tests it this week to see what's improved.
