Just to clarify that nugget of misinformation...I can assure you that Optimus is not just for Windows. Off-topic, but perhaps helpful to someone lurking: For about a year I have used a very functional Optimus-switching Ubuntu 12.04 LTS running on a Dell XPS 17 L702x laptop using Bumblebee. While I got Bumblebee to work under Fedora, kernel upgrades (which are fast and furious on Fedora) always broke X11; on Ubuntu it's been a non-issue, probably due to that's the distro the Bumblebee developers use. I get fantastic battery life (8-10 hrs w/12cell battery) and fans never cycle even after several hours of lightweight email/web use. Perfect this application!
