Just couple of quick questions - Due to job change, I will have to relocate to Shanghai from US, and I was thinking of bringing my 24'' iMac along with me. 1) I heard in China the voltage is 220V and it is 110V here in the US. Will it cause any problems for my iMac? 2) Should I mail the iMac or should I bring it with my on the plane? Thanks for any input.
