Notebook PC evolution is driven primarily by users who demand the ultimate performance for business purposes, personal use or both. They covet portability, battery life and high performance. Because many of these users are on the go, battery life is extremely critical. One outcome of Moore's Law is that we have become increasingly spoiled by ever-increasing performance milestones.
Mobile computing is no longer synonymous with performance sacrifice.
In fact, as notebook PC performance levels have increased, so too has the tendency for many to replace their desktop PC and make a notebook PC their single platform for both office and travel. Much has been written about Moore's Law, and it is as true today for mobile CPUs as it has ever been. A related trend is that as process geometries continue to shrink, the number of CPU transistors continues to increase, virtually doubling every two years. Moore's Law has been fairly accurate in predicting both of these trends. I've had it.
