He is referring of course to the PowerPC architecture. It did not have a performance lead over Intel for as long as you suggest. Even when it had a lead, it wasn't that big. (I bought the best G5 when it came out, so it's a painful memory) The problem with switching to a different architecture is that if it falls behind Intel, people will say "not as fast as a PC." If you stay with Intel and it falls behind, people say nothing. It's risk vs. no reward.
