I have used an OS from Germany that gave you the options of English or American for language LOL
An important distinction. I was working at SHAPE and driving the roads in Belgium after hours. I saw in interesting billboard with French language. I stopped by the mini-mart outside of the cafeteria at SHAPE and grabbed an English-French dictionary. Tossed it in my backpack. After work, I pull the dictionary out at the hotel room and looked up the unfamiliar French word. The English equivalent was "bloke". Damn. British English, not American English. C'est la vie!
