A prototype of the next-generation PC. Unveiled by Microsoft and HP in the spring of 2003, an Athens device integrates a telephone handset, video camera and buttons on the keyboard for common functions. An Athens PC is quieter, smaller and sleeker than a typical PC, somewhat reminiscent of Apple's G4 Cube. It uses a large, landscape-style flat panel display and connects to a company's PBX. Athens may be released with Microsoft's Vista (Longhorn) OS. See Windows Vista.
