In UK, they all ship with Windows it looks like. The only laptops I found that don't shove the cost of a license down your throat are the build-your-own ones, like pcspecialist.co.uk / novatech.co.uk / scan.co.uk / ebuyer.com etc. But you're not gonna get thin portable laptops by building your own.
It's perplexing how we've let it come to a state where you can't buy a laptop device without Microsoft taking a cut for the license.
And I'm still not over the way we let them have their OS logo on all keyboards, either.
