The VGC-M53 is a personal computer with a compact and integrated main unit, screen and keyboard. The keyboard is retractable, and when not in use, can be folded away to make this PC fit compactly in any spare space as exactly as books or reading lamps do. The connection ports are positioned on the side so that no cables protrude from the back of the machine, allowing it to be placed against a wall. This means the folded VGC-M53 can be put in a narrow space no more than 20 cm deep. Equipped with a subwoofer, the VGC-M53 is able to play music with high-quality sound. The VGC-M53 is also designed to be enjoyed when not in use as a PC. By means of an application (Sound Flow) that automatically starts up when the keyboard is folded away, a music player interface, clock, calendar, and other functions are displayed on the part of the screen that is not hidden by the keyboard.
