Apple products are more expensive in Europe because you pay for VAT (for example 20% in the UK), and because you have better consumer protection laws in the EU.
You will be able to get the 20% VAT back, but Apple will likely not be helpful. And the consumer protection laws won't help you, because Apple is not responsible to fix problems for up to around 2 years, but the store where you bought, which would be somewhere in Europe. In addition you need new plugs, and you are unlikely to be able to buy a device with a US keyboard.
