Nvidia introduces Project Shield, an Android-powered gaming device that represents the brand's first ever consumer electronics product. Using Nvidia's new Tegra 4 chipset, the device features a 5-inch 720p touch-screen and can play both Android and PC games. The controller is finished in matte black with chrome accents, equipped with analog sticks, D-pad bumpers and controller buttons. But Project Shield isn't just a foray into portable gaming, as it can be viewed as taking a shot into the tablet marketplace, capable of playing 4k movies to a full 4k TV via HDMI, checking email, multitasking while playing music in the background -- essentially anything you can do with a modern tablet or smartphone. It connects to the Internet with Wi-Fi and has battery life good for five to 10 hours of gaming, or displaying HD video for 24 hours. Stay tuned for pricing and release details.
