With the official public release of information on their new Tegra 4 processor, Nvidia has also released information on their 'Shield' device.
Not sure how big a deal this is, but it's an Android with WiFi device, with a multi-touch display, 720p resolution and access to the Google Play store. There is also an Nvidia store, but it's not locked into their store only (smart). Pics of the device show a mini-HDMI port, usb port and a headphone jack.
No word on price.

Almost forgot. You can stream your PC games and play them over WiFi. This includes Steam games apparently. That might be a big deal.
