I remember that the Rev A. iMac didn't have a 100-240v Powersupply. You got whatever our country used. I noticed that the new intel version ( and the previous rev c G5 version) states 100-240v. Is this just a way to save some space on their page or do the new iMacs come with switching Power supplies? I plan on taking a 20" to China with me but need to know about this before I buy. I thought I'd ask here before I call apple.
