Intel's Developer Forum in Beijing has slipped out a new set of guidelines for Intel-based Windows 8 tablets. The chip designer wants tablets based on its Atom Z2760 chip to largely fit in with a 10-inch, touch-only tablet or a 11-inch version with a keyboard, CNET saw in its copy of the hardware advice. All of the dimensions would be targeted at matching or beating the iPad, with weight under 1.5 pounds, thicknesses below 0.35 inches, and over none hours of at least theoretical battery life.
