OEMs are taking advantage of Intel's new Haswell chips by announcing new tablet devices and upgrading current available devices with the new CPU. Sony is the latest OEM to launch new Intel Haswell-based devices in the form of the Sony Vaio Duo 13, Vaio Pro 13, and Vaio Pro 11 Windows 8 ultrabooks.

The new Ultrabooks announced by Sony are the Vaio Duo 13, Vaio Pro 13 and 11. These new Vaio models can be converted into tablets, which is good for those times when a user just wants to play with the touchscreen without any obstructions from the keyboard. Furthermore, the Vaio Duo 13 will come bundled with Sony's digital stylus, too bad this stylus is not bundled with the other offerings.

"Our aim with these unique new models is to provide customers with a variety of new ways to use their PCs. We have achieved this by combining powerful Sony technologies with new form factors," said Ryosuke Akahane, SVP and President of VAIO & Mobile Business Group, "We're aiming to make devices that will enhance and enrich individuals' lifestyles in both work and play. One example of this is the VAIO® Duo 13's camera functionality. It has the ability to take crisp images of documents using the computer's camera as if it were a scanner. Images are clear enough to recognize and tag text, allowing for easier, more effective and efficient searching and editing."

The most powerful of the three devices is the Vaio Duo 13, which comes with a 13.3-inch display that is capable of 1080 video playback. The device also comes with an 8-megaixel camera with Exmor R sensor, an HD webcam, HDMI out, a 512GB hard disk and Sony's "innovative standby technology" that allows for the device to wake from sleep mode in just a single second.

The Vaio Pro 13 and 11 on the other hand is very similar to the Duo 13 in regards to specifications, with the main difference being the weight and screen size. The Vaio Pro 13 and 11 weighs just 1.06kg and 0.87kg, respectively, the display size comes in at 13-inches for the Vaio Pro 13, and 11-inches for the Vaio Pro 11. In addition, both device have longer lasting battery life compared to the Vaio Duo 13.

Potential buyers should expect to see these devices on store shelves by the middle of June for an unannounced price.
