Change of strategy
Traditionally, Apple has not acquired large scale companies - instead buying smaller companies with specific technologies, and folding them into the business.
One recent example of this is Siri, a company Apple acquired in 2010 when it wanted to provide an integrated personal assistant on its iPhone and iPad products.
MrSculley said that while he had "no insider knowledge" of the firm he left in 1993, he said he now wonders if it is time for Apple to change its growth strategy.
"Apple's never been an acquirer of big companies before, and when you look at the [Apple digital ticket system] Passbook, and fingerprint recognition - what would it mean if Apple went out and bought eBay? And they had PayPal, and integrated that?
"My guess is you'd suddenly see the whole landscape of e-commerce shift.
"You have Amazon, which is on the fast-track to dominate every aspect of e-commerce - suddenly the game, the landscape, would change."
