There's no way I would use this if I were in front of my PC, that's where KB+M will always be 1000+ times better. I would only use this thing when playing on the HDTV in the living room, playing slow games, which is where this kind of devices belong. These devices + fast paced FPS playing == FAIL. Looking at the videos posted above it clearly is not nearly as accurate as a mouse (in fact it doesn't look much more accurate than a controler) and most importantly you cannot make 180-360 degrees turns easily or at all. FAIL.
