If you’ve been mourning Sony’s decision to discontinue its super-thin Z Series laptop, you can at last dry your tears: the company just announced two flagship Ultrabooks that should more than make up for your loss. For starters, the VAIO Pro 11 and Pro 13 each weigh less than the Z, at 1.92 and 2.34 pounds, respectively — in fact, Sony claims they’re the lightest touchscreen Ultrabooks ever made. They also last longer on a charge and have an optional sheet battery that promises to double the battery life, providing up to 14 hours on the Pro 11 and 13 hours of use on the Pro 13. Presumably, they’re faster too: both ship with Haswell processors, and the 13-inch version in particular will be offered with PCIe solid-state drives. And, lest you worry Sony evolved the Z too much, its flagship laptops are still made of carbon fiber from top to bottom.
