@LorenD: "For the record, I've never had a WLAN issue in 3 years of Linux (Ubuntu and then openSUSE). I can't attest to GPU as I don't have a dedicated GPU though.

GRUB has also been quite the happy camper in my experience (at least if you don't go mucking about with config files)."

How dare you not have a problem in a discussion on Linux. (Not just there yet :)
