I ordered the North American Version (US keyboard- there is an option on the order page), but it really has no difference in OS.3.1 and up, just hold both mouse buttons down at boot, and boot into the mode you want (PAL or NTSC). I have a "UK" version of the A600 here and other than the boot, there is no difference in my opinion, just use a power supply that is for your country. I have a North American Power supply on my A600 and it has no issues at all.
