The Spectre XT is a thinner and lighter cousin of the Spectre 14, which was introduced earlier this year. The Spectre 14 has features including wireless audio and NFC (near-field communication).

There is also a healthy demand for ultrabooks in enterprises and HP is building up the product portfolio, said Scott McCammon, worldwide product manager at HP. The company currently offers the Folio 13 ultrabook, which started shipping last year.

HP on Wednesday also announced the top-of-the-line EliteBook Folio 9470M ultrabook, which has a 14-inch screen and offers nine hours of battery life. The ultrabook is priced starting at $1,149, and will ship in October. The ultrabook is 1.6 kilos, 19 mm thick and can offer nine hours of battery life. An optional slice battery gives the laptop 20 hours of battery life.
