Maximum PC: It's been rumored that Apple is going to come out with a 12.9-inch iPad Pro tablet, but while iOS fans wait for that day, Android users have another large size option in the new HP Pro Slate 12, one of many mobile devices the company officially launched today. There's also a smaller 8-inch version (HP Pro Slate 8), both of which are powered by an Qualcomm Snapdragon 800 series processor and 2GB of RAM.
