You do need a UK and US version of your site if you sell things in both countries, but that's usually a region selector where you don't use the HTTP language system. If you did then anyone with their language set to en-US would see the American site even if they live somewhere else.
Instead we have google that would serve the pages based off the local ip (and switch any time possible) which is a "horrific" experience travelling through Europe. You get a different language every day. Totally ignoring the accept-language header.
It's even funnier as the roaming would result in having the host mobile network IP regardless where a person resides - still ignoring the lang header, of course.
