Intel and HP have showcased a jointly-developed concept PC, Deep Forest. The PC prototype uses Intel's Pentium 4 processor and the AGP4X graphics chipset to handle the increasingly heavy graphics load involved in Web browsing. The PC boasts seven USB (Universal Serial Bus) slots for expansion options. At 13-x-10-x-4 inches, the PC could be used not only for computing but also as a photo frame or paper tray, the companies said. The PC will not go on sale anytime soon: Intel and HP see the design as a step toward the future and are looking for others to help refine the design.
