HP Envy15

HP is providing a 15.6″ muscle computer with the Envy15. It features a Quad-core CPU, a discrete GPU (Radeon HD4330) up to 16GB of DDR3 memory ($$$), and it can accommodate two SSD drives in a RAID0 configuration to reach the ultimate hard disk performance on a laptop computer.

That said, it is only 1-inch thin and weighs about 5.19lbs. The chassis is made of aluminum and the design is quite nice. The HP Envy15 also features Beats speakers that should provide a better sound experience than most laptops with this form factor. Check out the Envy13 as well.
