Sony Vaio Pro 13/11 Ultrabooks
Sony may have delivered the best Windows-based competitor to the MacBook Air yet with the new Vaio Pro Ultrabook line. Built with carbon fiber, the Vaio Pro 11 weighs a mere 1.9 pounds and the Pro 13 just 2.3 pounds; both are 0.68 inches thick. Our sister site CNET has already secured units and provided some hands-on testing of the Pro 13 and a full review of the Pro 11. While the base MacBook Air models currently cost less than the $1,150 base Pro 11 and $1,250 Pro 13, they offer lower-res screens and less solid-state storage capacity. Of course, with rumors circulating that MacBook refreshes with Haswell processors could be due as early as next week's Apple WWDC, the Vaio Pro Ultrabooks could lose some of their competitive advantage.
Asus Transformer Book Trio
Leave it to Asus to do things really differently with the Transformer Book Trio, which takes the original Transformer Book and adds a third form factor. The Transformer Book combined a laptop with a detachable tablet, but now the Trio not only offers those two modes, but also allows you to connect it to an external monitor station to use as an all-in-one PC. You can even toggle between Android and Windows 8 when you're using the Trio on the go. While the notebook/tablet runs using an Intel Atom chip and offers up to 64GB of flash-memory storage, the PC station packs a Haswell processor and up to a 1TB hard drive. More on the Trio, which does not yet have a release date or any official pricing yet, from ZDNet's James Kendrick.
Asus Zenbook Infinity Ultrabook
If you think the Sony Vaio Pro laptops are thin, the forthcoming Zenbook Infinity has them beat by a few millimeters. The new Ultrabook will be just 0.61 inches in thickness. While Asus had the notebook on display at Computex, precious little else is known about it, though it is built with the third (and latest) version of Corning's Gorilla Glass. Despite its beautiful exterior and new Haswell-based interior, the Zenbook Infinity might face difficulties related to Microsoft Windows 8 and the overall PC landscape, according to ZDNet's Larry Dignan.
