Apple shunned superstar chip start-up for Intel

"PA Semi - a maker of low-power Power processors - formed a tight relationship with Apple - one meant to result in it delivering chips for Apple's notebook line and possibly desktops. The two companies shared software engineering work, trying to see how Apple's applications could be ported onto PA Semi's silicon. When word leaked out that Apple had signed on with Intel, it shocked the PA Semi staff, according to multiple sources."
