10 years on, Apple's risky move to Intel Macs is one of its biggest successes

Nine years ago today, Apple launched the very first iPhone. But the foundation for its success had actually been laid a year earlier. Ten years ago, in the summer of 2006, Apple had just successfully transformed the Mac, completing a transition from using PowerPC chips to Intel chips and essentially transplanting the the "brains" of its entire line of personal computers. The transition, which was first announced at Apple's Worldwide Developers Conference in 2005, was a big deal. Apple was moving from IBM-built PowerPC processors in its Mac computers to x86 processors made by Intel.
