Perhaps it's a cheap shot, but he apparently doesn't know what ISA stands for - it's glossed as "Industry Standard Architecture". I think you're off base on Apple's ability to port to a new (or old, for them) architecture and handle app translation on the fly. They've done it twice before with very good success and OS X has the infrastructure to make it as easy for them as it's likely to be for anyone.
