Can't decide whether your next computer should be a laptop a desktop? Now you don't have to decide. HP has released its largest laptop yet, the HP Pavilion HDX, which features a 20.1-inch LCD and weighs a hefty 15.5 pounds. This semiportable home theater system is based on Intel's new Centrino Duo platform (a.k.a. Santa Rosa) and boasts a Media Center remote control that docks next to the full-size keyboard, an HDMI output, and an optional HD DVD drive.
