It’s fair to say that if you repeat a somewhat reasonable rumor about Apple year after year, it might eventually come to pass. So as its ARM-based CPUs have become more and more powerful, it seems a given that Apple is poised to ditch Intel one of these days and make the third processor switchover in its history.
Now when Apple first moved to the PowerPC in 1994, it didn’t seem so much of an issue at the time, although it survived for 12 years. But the Intel rumors were around for quite a while. One of the most interesting ones focused on Apple having a secret project, “Star Trek,” where new Macs were being tested with Intel CPUs at the same time that Steve Jobs was reassuring everyone that they were perfectly happy with the progress of the PowerPC.
Lest you forget, the most powerful Macs with the G5 required liquid cooling to keep the chassis from frying. It was never tamed for notebook use, so year after year the fastest PowerBooks lost traction against even cheaper Intel-based Windows portables.
