We've learned that many OEMs are not so keen about the Hybrid SLI, as you apparently need to reboot the machine to switch from discrete to integrated graphics; you cannot do it on the fly.

This might not be the case with the final units, but apparently OEMs simply cannot find the place in their hearts for two graphics cores, one integrated and one discrete, as it will cost them more than just one of them.

Nvidia cannot sell them an integrated motherboard for a price of non-integrated, and this is where all the problems begin. We are sure that OEMs won’t be that hot for Hybrid Crossfire, but that is another story altogether.
