When Windows 8 systems started rolling out last year, it seemed like PC manufacturers spent all their efforts trying to make some sort of hybrid or convertible laptop. For their regular clamshell notebooks, the most they did was install Windows 8 and put in a touch screen.
But, based on the Sony Vaio Pro 13 Touch ultrabook (and its smaller linemate, the Vaio Pro 11), it looks like the wait for some interesting ultrabooks might be over thanks to the launch of Intel's fourth-gen Core i-series processors.
The carbon-fiber-constructed Pro 13 weighs only 2.34 pounds; it's 2.9 pounds with its power supply, which is as much as the 13-inch MacBook Air weighs on its own. The body measures 12.7 inches wide by 8.5 inches deep, which is fractionally smaller than the Air, and matches its 0.68-inch thickness.
If you don't dive deeper than base specs, the 13-inch Air and Pro 13 Touch match each other fairly closely. It's once you look at the Sony's fine details, you'll uncover differences, and in a game of specsmanship, the Sony wins. Still, in the end, they're both excellent laptops and it comes down to what you like and what you want to have.
