Blade's Shadow game streaming service is still young, but it's already getting a hardware upgrade. The company has unveiled a Shadow Ghost device that promises to deliver more flexibility and power than the Shadow Box. The curvy new design is slicker-looking, but also smaller, lighter and quieter -- Blade envisions taking it with you to a friend's place. It also includes Bluetooth and WiFi, so you don't have to string Ethernet cables or plug in wired peripherals. And if performance matters, HDMI 2.0 both enables 144Hz refresh rates and opens the door to gameplay on more screens.
