Surface Pro 2: WinTel Tablet
There is a growing consensus that Microsoft needs Intel's power-sipping Haswell processors in its Surface tablets to help it shore up its weak spots -- power and performance. It may also be a no-brainer, considering Intel's fourth-generation Core iX Haswell processor is already doing well in a number of tablets and convertibles.
The Haswell chip would allow Microsoft to make the case that the Surface Pro 2 is a laptop replacement (considering how many laptops run Haswell chips). Couple Haswell's power efficiency with the fact that the fanless chip would allow for a bigger built-in battery inside a tablet's tiny chassis, and you come a long way to fixing Surface's lacking battery life.
