HP originally unveiled the Slate 8 Pro and Slate 7 Extreme back in September. That announcement also included the Slate 7 HD and Slate 10 HD. But the key for today is the Pro and Extreme models as they have both begun to arrive with US retailers. Specifically, the Slate 8 Pro and Slate 7 Extreme are available direct with HP and also with big-box retailer Best Buy.

The Slate 8 Pro has an 8-inch display with a resolution of 1600 x 1200 as well as microHDMI, a 3 megapixel front-facing camera and 8 megapixel rear-facing camera.
