We already know Windows 8's bootup time is wicked fast. Now we know it's going to be wicked attractive too, with the same minimalist glory of Windows 7 Mobile and Metro. Goodbye, horrible decades-old DOS eye murder. Hello, beautiful booting.
That's Windows 7, not a mini-Linux OS like Splashtop. It's also from a powered-off state, not sleep mode. Pretty impressive. And much of that speed comes from turning on a laptop's devices (hard disk, ports, etc) in just 1 second.
