Shipping a US keyboard in Europe seems like an odd choice since most European keyboard layouts are ISO, not ANSI. I could see a blank keyboard working, or an ISO US keyboard maybe, but that is an uncommon layout that I don't think I've ever actually seen before?
Does this even matter? The point is that if one is fine with the US/ANSI keyboard, they should be allowed to buy it. To wit, I'm european and despise the ISO keyboards, and have never been forced to use one, so it's not like they're ubiquitous.
In many, many European countries, especially the smaller ones, a large chunk of devs and sysadmins straight out use the US keyboard layout, basically the old IBM PC one. I have no idea what kind of standard they follow... And people don't seem to care.
