That's a typical hardware company's response - deliver only half-baked functionality and leave the debugging to platform integrators. Nvidia reaps the marketing bonus points. Laptop companies have to put in the time to actually get the power savings.

Still, I don't think many people were aware that Linux wasn't (ever * ) going to work on Optimus laptops and notebooks - and Linus' comments have helped raise awareness of the issue.

* Until Linus and Nvidia make up.
