Looks like HP doesn’t want to lag behind, when Samsung and Toshiba, both plan to announce Windows 8 computers this week. All three Ultrabooks hope to offer tough competition to its competitors. Let’s take a look at the features of all three: The first one, HP Spectre XT is a 15.6-inch splendor, which will make an apt choice for those who always prefer their screens be attached to the keyboard. Truly pushing the limitations of an ideal Ultrabook, HP Spectre XT is thin and light. This Ultrabook boasts of a HD Radiance display with a resolution of 1920 x 1080. This touchscreen device weighs 4.8-pound and is 17.9 mm in thickness. You will be able to bag Spectre XT for $1,399.99. It will also feature HDMI, Ethernet, USB 3.0, and Thunderbolt ports along with NFC (Near Field Communications) for easy sharing with other devices. Then there is the HP Envy TouchSmart Ultrabook 4, which is a 14-inch laptop, smaller than the Spectre. With latest Intel possessors, this Ultrabook will be a cheaper alternative as compared to the HP Spectre XT. The price of this Ultrabook stays unrevealed. And, then it’s the HP’s Envy x2 hybrid PC that is made truly gorgeous with an aluminum casing. This sleek 11.6-inch Ultrabook can also pop out the screen so that you can use it as a fully capable Windows 8 tablet. This versatile and interesting Ultrabook cum tablet will have Intel third-generation processor with 64GB solid state drive. With a high-quality IPS display, and 3.1 pounds of weight, the HP Envy x2 hybrid PC has surely got all the attention and excitement. This PC also holds batteries and SD card slots in both the keyboard and screen portions. Pricing and availability of the Envy x2 haven’t been announced as yet. But it is believed that all these Ultrabooks will hit the market this October, with the launch of Windows 8. A look at these Ultrabooks makes it worthwhile to wait for the launch before deciding your pick!
