In the wake of Dell's addition of Penryn to Inspiron notebooks, systems from Gateway and Alienware have also been upgraded with the Intel processor technology. Alienware's Area-51 m15x has been given the option of a 2.5 or 2.6GHz Core 2 Duo, or else a 2.8GHz Core 2 Extreme; its display measures 15.4 inches, and costs start at $2,149. Gateway's contribution is the 17-inch P-171X FX, which uses a 2.4GHz Core 2 Duo chip and is priced at $2,000. The company adds that an M-series notebook will also be equipped with Penryn "in a few weeks," but refuses to disclose further details. [via Crave]
