Sony is said to be among the first manufacturer to take advantage of Centrino 2’s ability to switch between graphics chips with its Vaio Z570. Back in the days, “thin & light” (<4lbs) laptop users complained about having to choose between a decent graphics chip and a better battery life. The solution was to make manually switchable graphics: the user had to physically move a switch, and then reboot to use a different graphics chip. As we covered during the Centrino 2 launch, things ate getting better: the system can now switch between integrated (low power) and discrete (high performance) graphics without rebooting. This is indeed a huge progress, as most people would not reboot, unless they direly needed more battery life.
