Similar dual-GPU features have been around for a while, such as the MacBook Pro's ability to switch between the GeForce 9400M and 9600M, but that requires users to log out. The beauty of Asus' implementation is that it's virtually user-transparent, switching on its own.
The GPU swapping, dynamic clocking, and other power management features allow the UL80JT to consume less than half as much power as the unibody MacBook while browsing. Despite that, the system can instantly kick into high gear, with performance matching similarly-specced laptops.
Asus plans to launch the UL80JT this year for just over a grand.
