HP has introduced a batch of new ultraportable laptops including the top-line Spectre XT.

Following on from the original HP Envy 14 Spectre, the XT slots in above the rest of the range.

HP also introduced us to a new and bound-to-confound word –Sleekbook. You see, it seems the Envy 14 and 15 will be available in both AMD and Intel versions – and since Intel owns the Ultrabook name, HP has used Sleekbook as the name for the AMD versions.

Confused? You're not alone; it took us a fair while to get our heads around the crazy marketing when we were introduced to the new laptops at an HP event in Shanghai this morning.

UPDATE: It seems there will be 14-inch and 15.6-inch versions of both the Envy Ultrabook and Envy Sleekbook - full specs at the bottom of this article.

There was also something for business users, too; HP also took the wraps off the 14-inch, 1.6Kg HP EliteBook Folio – also an Ultrabook, it features a TPM (Trusted Platform Module) chip so it can be remotely managed.

Thin, but not too light

The Spectre XT is 14.5mm thick and weighs in at 1.4Kg – as with the original Spectre, this is pretty heavy for what is a premium Ultrabook. The various versions all feature one of the latest Intel Core processors.

In terms of other specs, the 13-incher features up to 256GB SSDs and up to eight hours of battery life plus an impressive four speakers. There's also a full array of ports, including Gigabit Ethernet, USB 3.0 and HDMI. The Spectre XT also offers two years of Norton Internet Security plus full versions of Adobe Photoshop Elements 10 and Adobe Premiere Elements 10.

The new Envy Ultrabook and Envy Sleekbook models are from 19.8mm tick and weigh from 1.79 kg. Again, these feature the latest Intel Core processors or the latest AMD Accelerated Processing Units (APUs) and boasts up to eight or nine hours of battery life. All also have two speakers and a subwoofer,

All the new Envy and Spectre models feature Beats Audio and Intel variants have the company's Rapid Start Technology.

The Envy 14, Envy 15 and Spectre XT UK release date is June. Prices clock in from £899 for the Spectre XT.
