My bad, I didn't write everything... I agree with you, as what you mentioned is the very purpose of optimus.
My point is that nvidia doesn't make clear in the docs (support, website, etc..) that under linux it is not a matter of installing the driver and you're good to go.
If they can't make their driver work, for whatever reason, I only see two ways to go: mandate the switch, or say out loud that the linux support they provide is _crap_ (ok, 'user-dependent' or 'must rely on 3rd party tools' would be more politically correct). The fact they didn't do either is reason to blame.
At least, some nb makers are using the switch in certain models (lenovo's workstation is, but its snb, not ivb).
