Yeah, that Return key is bizarre... but it's no newsflash that Apple are fiercely US-centric and don't give a crap about other countries, but they still want their money so they put in just the minimum effort needed to get by.
Many OSX translations are pretty lousy. iWorks is only available in English, French and German, while M$ Office is available in any obscure language of your choosing. It took aeons for the Weather widget to recognize any location outside the US (when I tried to set it to Stockholm, Sweden it would point to Stockholm, New Jersey). The iTunes stores outside the US carry pretty much nothing, especially in terms of video content, but Apple tries to cram Apple TV down European throats anyway. And don't get me started on the iPhone which was tailor made for some outdated network type used only in the US, and legacy supported in some European countries. Took them a year to figure out what the rest of the world uses. You never see such cocky nonchalance from companies like Microsoft, Logitech, Dell, HP or others. And now that the US dollar is barely worth the paper it's printed on, you'd think Apple would seize the opportunity for some competitive pricing in Europe, for once, but instead they're seizing the opportunity to make extra extra truckloads of cash, leading to the worst US vs. International price ratio in the company's history. In Sweden, the Mac Pro starts at the equivalent of 4000 USD... that's the US price + 43%. Yeah, go ahead, rob the eurotrash...
