Anyone know anything about MBAs with Spanish keyboards?

I'm based in Manila, Philippines. Imagine our surprise, when we bought an MBA still sealed in its box, to discover the documentation all in Spanish, and the keyboard is physically different - different layout, different key assignments stenciled onto the keys, different Enter key. It's not just a matter of changing keyboard layouts in Sys Prefs. Didn't even know there were such things. Trying to get it exchanged for a regular English unit, but so far no good.

Does anyone know anything about this variant of the MBA? Been looking around the net and there doesn't seem to be anything about it at all.
