HP Ultrabook
HP EliteBook 2170p
The Elitebook 2170p is not exactly an ultrabook at its soul but is still quite thin and ultra portable. Being 1.1 inch thick, it is the HP’s lightest and smallest business laptop. Its lid is tad plastic and aluminum as you would expect from a $1000 ultrabook but do not fret – this Elitebook is made from high quality plastic. Battery life is said be around 6-7 hours and 9 hours with power saving feature on.

HP EliteBook Folio 9470m
HP Folio 9470m is an ultrabook with 14 inch display meant for serious business. While it is not as light as the HP Envy Spectre XT, it is mere 0.7 inches thick and is still somehow to carry full size ports like VGA, display port and Ethernet. Oh, and it has removable battery, something that is missing in almost all ultrabooks.

HP Envy Spectre XT
HP Envy Spectre XT is a very powerful ultrabook packing the latest Intel Core i5 3317U processor, beats audio and super fast SSD. You will fall in love sleek design and amazing battery life. Its screen, like most ultrabooks is lackluster and low resolution. The fan is said to be loud too.

HP Envy 6
With the HP Envy 4 ultrabook, the company achieved a super affordable price tag by doing serious sacrifice to quality by not bundling any sort of SSD inside. This made some die hard ultrabook users angry as one of the key components that set ultrabook aside from normal notebooks was inclusion of SSD. To those, HP is now offering Envy 6 ultrabook. Powered by Intel Core i5-3317U, an Ivy Bridge processor, it features a bigger 15.6 inch display with 1366 x 768 pixel resolution and yes, a 32GB SSD too along with 500GB hard disk.
