HP's powerhouse laptop sails through performance tests and whips the current competition. If speed is what matters to you, the Pavilion dv7t has it in spades. Beyond the 17-inch screen and under the cool "liquid metal" exterior lies Intel's new Centrino 2 processor. The result: high-octane performance in an extremely shiny package. The dv7t, with its 2.53-GHz Core 2 Duo T9400 processor and 3GB of RAM, turned in a blazing score of 98 in our WorldBench 6 tests. Interestingly, MicroExpress's identically stacked all-purpose machine, the JFL9226, earned a mark of 103. The dv7t is a handsome, fast unit. For our review it was nicely configured with a 400GB hard drive, a Blu-ray drive, and Windows Vista Home Premium. And if you're looking to replace a desktop, it's a better candidate than most other big notebooks because of its proprietary left-side connection for HP's xb3000 expansion base. Though the base is an expensive add-on, it incorporates a screen stand, a third hard-drive bay, far better speakers, and a wireless keyboard and mouse for a complete desktop experience.
