In a few weeks I'm planning on buying a snazzy new 27" iMac, and assuming the US/AU dollar stays near parity, I've thought about buying it from the US and having it shipped over to save a few hundred dollars. I'm just wondering if there is anything I should know about doing something like this, especially in terms of the power supply. Obviously I'll need to buy a new power cable to use in Australian wall sockets, but does the US have a different power voltage or something than Australia (in other words, will my US iMac blow up if I plug it into my Aussie socket?). Also, will buying it from the US affect my warranty? And are Apple nice enough to ship it to me for free? I'd really appreciate any feedback from those of you who have done the same. Edit: ok so after doing some proper research on Apple's site I see that they won't ship outside the US - so can anybody recommend a method to get around this?
