A few years from now, your vacation might take you to a room much like number 267 at the Hilton Garden Inn at LAX/El Segundo. As you enter, motion sensors automatically turn on the lights. You touch the biometric safe with your thumb, and the door opens to store your valuables. You flop on the bed, and its system of slats and air pockets molds to your body's weight and contours. Your remote dims the lights, opens the drapes, checks your e-mail on plasma television, and changes the digital artwork on the walls to suit your tastes.
