The Dell XPS 15, we praised the notebook’s strong performance, best-in-class audio, and colorful screen. Now Dell has upgraded its premium 15-inc her with Intel’s second-generation Core Series processors and Nvidia GeForce GT 500 series graphics. We also like that the matte finish continues on the sides and bottom, areas too often ignored by other notebook makers.We consider temperatures below 95 degrees comfortable.Dell backs the XPS 15 with a standard one-year warranty on parts and labor.
