The key issue for anyone planning to travel is that an Apple laptop will work pretty much anywhere, and you don't need to do anything about voltage or frequency. I just returned from a trip on which I used my MacBook in London, Istanbul, and Turkmenistan. All I needed was the standard European plug adapter. In some parts of the world it may be advisable to carry a small surge protector to protect against spikes, but that's a different issue.
