dual-core laptops at CES. Gateway is showing off two dual-core portables of its own: the business-oriented M685-E and NX860. Both will be powered by Intel's Centrino Duo processors, and will include 17-inch displays, will include nVidia GeForce Go graphics controllers, and will weigh roughly 7.7 pounds. Both models are due out later this month. Gateway will also roll out a series of consumer dual-core laptops later this quarter, incuding the NX560, which will feature a 15.4-inch widescreen display.
