Sony Vaio Duo 13 Ultrabook
The Duo 13 is an update to the Vaio Duo 11, which Sony released several months as a Windows 8 laptop that uses a sliding hinge to switch into tablet mode. The new version maintains the same convertible design with a bigger full 1080p HD touchscreen and upgraded Haswell processors. As the image above shows, you can use the included digitizer pen to input on the screen, or you can just make use of your fingers. You also get a rear-facing 8-megapixel camera that incorporates Sony's Exmor RS for PC image sensor. Our sister site CNET has a hands-on with the Vaio Duo 13, and still bemoans the inability to tilt the screen, while finding the slider mechanism and touch pad much improved.
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.
