The ET Project device was a handheld gaming console roughly the same size as Nintendo's original GBA, and came with a colour LCD screen and a Memory Stick slot for loading games onto the device. Interestingly, Sony planned for Memory Sticks to be reusable in the console - gamers would be able to load new games onto their Memory Sticks at special kiosks in shops for a fee.
