HP looks set to launch a new Ultrabook later this year after the PC manufacturer posted a video teaser online.

The video clip, which can be viewed on YouTube, keeps things brief but teases us with lines and silhouettes of a new device called the HP Spectre. The shapely design and thinness of the computer leads us to assume it is HP's next assult on the Ultrabook market.

Ultrabooks are a new category of thin and light laptops, which were introduced by Intel last year. The laptops, which are laptops under 20mm (0.8in) thick, "marry the performance and capabilities of today's laptops with tablet-like features" and are designed to offer a happy medium between laptops and tablets.

Ultrabooks run on Core processors, and the company aims to roll out advanced designs with features such as touchscreens, all-day batteries and instant-boot capabilities over the next few years.

Intel hopes Ultrabooks will make up 40 percent of its consumer laptop sales by the end of next year. Intel has pitched the initial price of Ultrabooks at around $1,000 (£645), but some analysts believe the price may not go down well in a slumping PC market where buyers are looking for deals.

Roger Kay, president of Endpoint Technologies Associates said the initial pricing is unlikely to help Intel redefine the laptop market.

"If there's any fly in the ointment it is the price. Even though they are great packages, you are talking about $1,000," Kay said.

Lenovo, Acer, Dell, Toshiba and Asus are among the first PC vendors to offer Ultrabooks, although with CES just days away, we expect many more to be announced.
