hey everyone... i'll be handing my 13mbp down to my wife whose mb went belly up, and i'll be grabbing a new mbp. so i have a question... from what i understand, i could copy everything over by either migration assistant or time machine. i'll be prompted in the beginning to choose one or the other. i use tm anyway every few weeks, and i'm prepared to do it again in the next day or two. so what are some of the differences between these two techniques? tm will do an exact copy over to the new hdd, right? what is the end result of migration assistant? does it or doesn't it result with the new machine looking identical to the old one? i understand that migration assistant requires connecting the two. what would be the time differences between the two? approx 200gb of this and that. is one faster than the other? any other points to consider? much thanks!
