I have a macbook here that I bought last time I was in the states and brought into Prague airport. Instead of using the box, I bought a $30 neoprene gel case from the mac store and I love it. It's really compact so it still fits in my little sling bag and it's pretty tough, surviving a few clumsy drops with aplomb.

As far as compatibility, you should be fine with an adapter. i believe there is a converter built into the charging cable. I've had my comp here for about 9 months now and so far no problems. *knock wood*

Mac is still relatively new here, however, so if you need any parts it may be hard to track down as there's like 3 mac stores in the whole city.
