From Game Tex Japan comes the Flexible holder which has a stand for the PSP on one end and a suction cup on the other. The arm is around 17 cms long and can be turned a full 360 degrees. With the soon to be available GPS add on you can hook the PSP to your car's windshield and zip around town. There are tons of combinations of using the holder like sticking it to your bed to play MGS or watching a movie on the UMD and the craziest of all placing it next to the kitchen sink to catch a flick. You dont have to worry about the PSP falling down as the suction cup is very strong.
