I admit I haven't followed graphic card technology as much as in my college years (I know, I should turn in my geek membership card). However, from what I'm reading, it seems like switching between the graphic cards, as well as Hybrid SLI not being enabled in the new MacBook Pros, is more of a software than a hardware issue. 2 questions (for those more knowledgeable than me): * Can Apple/nVidia eventually change the drivers so that a logout will not be required to change between the cards? I assume they can. * Can nVidia ship a driver for the new hardware that would enable Hybrid SLI?
