Some OEMs with some models here in the USA also offer it. HP and Dell offer it. I think Dell gives Fedora and Ubuntu? And it takes off ~$130 USD or so from the price, so it's the full Windows license cost.

Personally if I have that option I'm taking it and just reinstalling whatever I want anyway, but it's nice having that option.

Also if I'm going to spend $2k+ on a new laptop and they don't give me a non-Windows/blank OS option then I'd go to support and request a special product link. Otherwise I'll find another brand or buy used.
