How come it doesn include a built-in hardrive?
The XO laptop is designed without a mechanical hard drive in an effort to minimize the number of moving parts, to make the laptop more rugged. By some estimations, the mechanical hard drive in a typical laptop is its most fragile part; it can fail after being bumped or dropped, especially if it is reading or writing data at the time. Instead, the XO laptops use an internal flash drive for storage—flash memory is nigh-invulnerable to bumps and falls, and it consumes less power, too. (see also Hardware uniqueness.
