that's why they call it, or market it, as the SIXAXIS controller.... the ps3 is a more adult oriented system (mature gamer) because you just hold the controller still while pressing the buttons... the wii is for those you can sit still just pressing buttons on the controller therefore aimed towards the younger (less mature gamer) crowd. Hey I went through that phase when i first started gaming on the 8-bit Nintendo system back in the late 80's... i'd sometimes try to flick my controller up while breaking a box with mario or steer the controller when playing "tyco rc".... as a casual gamer of FPS and racing games, i'd still prefer playing most games with the motion sensing off....
