I don't doubt that this controller design likely won't cut it for precision FPS play. On the flipside, however, having a giant keyboard, plus a mousemat taking up space (and to work well, a mouse needs a significant amount of space) and flopping around when people sit up and down on the couch may work for hardcore gamers, but it's likely a non-starter for anyone else. Even if you integrated the mouse so it could be on your lap, it would still be a large ugly thing that's likely to fall down and is hard to use in many of the relaxed positions people are used to gaming in.
