Acer, Dell, HP, Lenovo - you CAN'T find any for sale in any shops around here without Windows on them, and finding any without Windows on their websites is damned hard as well.

It reminds me of the early days of WGA on XP, it was SO touchy that it kept declaring valid systems as a pirate because you replaced the hard drive or video card or similar. Experience showed that the only version of Windows WGA could NOT shut down were the actual pirate copies as they didn't have the code to allow the shut down in them.
