Don't get me wrong, I use the binary blob on my desktop and am very satisfied with it. But on a laptop with Optimus, I wouldn't even bother trying to use VDPAU and stuff like that under Linux. You'd think if they had an opportunity to just pass the problem off to the Nouveau devs and wash their hands of it they would be all over it. As it stands, I would never purchase a laptop with an Optimus setup in it, despite the continual improvement in bumblebee that I keep hearing about.
