>The SE (and the II) have "switching" power supplies. That means that >they will automatically switch between 110 and 220; they can also >automatically work with either 50 or 60 Hz. The plus will not do this. A nit: Using conventional terminology, _all_ Macintoshes have switching power supplies. This term refers to the type of circuitry used to implement the power supply. It is possible to design a switching power suppply that does not care whether it is fed from 110 or 220 volt mains. Apple has chosen to do this for the SE. Another term should be used to describe this (dare I suggest 'universal switching power supply'?) It is also quite possible to design a non-switching power supply that does not care whether it is fed from 110 or 220. (Not necessarily efficient or cheap, just _possible_.) +----------------+ !
