Known only as “Project Fiona,” Razer’s concept tablet comes fused with a pair of game controllers on either side, each with a thumb stick, four face buttons, triggers and a bumper button. Razer plans to turn the concept into a Windows 8 tablet that can play high-end PC games, and the company will be gathering feedback to figure out things like thickness vs. performance and whether the controllers should be detachable. A finished product should be out by year’s end.
