No, you don't need it, but IMHO it is a good idea. When you're running the Mac at 120V with a power supply with a tolerance of up to 250V, a small power spike (30-40V say) won't cause you trouble. When running off 220-240V though, a power spike of that magnitude can toast your power supply. Add that to the fact that you are in a foreign country (meaning of course expensive repairs) and it's worth the security. I speak from experience. It happened to me once. Then I put a transformer on the damn thing and it survived every spike thereafter. -Ivan Internet: captkidd@athena.mit.edu
