a couple of times, yes. apple has a pretty good track record overall when dealing with these transitions. typically it's been to a platform that has been a strong improvement. if apple's making the decision to transition again, they must feel that it's for a very compelling reason once again. we don't have our hands on their current tech to agree whether it makes sense as a cpu upgrade, but likely it would make sense as a battery upgrade. whether that's a good enough reason to risk a transition, we will have to wait and see. personally, I've been burned too many times on first-gen apple hardware to jump on the bandwagon immediately, so am taking a wait and see approach. previous transitions that have been successful: m68k -> ppc ppc -> x86 x86 -> x64
