NVIDIA brought its new Shield handheld gaming system to Google I/O this year and showed off a near-production device. The Shield made its debut at CES this year, surprising most since it’s a consumer handheld device from a company that generally makes internal components. But it has some neat tricks up its sleeve, including a Tegra 4 chipset, 2GB of RAM, a 5-inch 720p display and 16GB of internal storage.
