I really like the Sager 8690, and can deal with the short battery life, but I really like the idea of the laptop switching between a lower and higher end GPUs as needed to conserve battery life. After all, any extra mobility on the go is a plus. I'd love to have one single laptop I can use for both general purpose work (web, email, text processing, etc) and high end gaming/work (photoshop, Maya, etc) without worrying about where to plug in. The sweet spot would of course be about 3-4 hours without plugging in for low level activity. I think it was something like intel's new Sandy Bridge platform would bring optimus to these higher end PCs. This releases around January 5th according to reports. AMD has a similar CPU+GPU platform coming out that could also have its own form of Optimus, although I haven't read anything saying it would do this. Has anyone else heard anything along these lines?
