Expect Apple to iterate, because that's what Apple does. Refreshingly sensible Apple commentary from Ars Technica.

It would certainly be great for tech journalists if Apple put out a completely redesigned iPad every six months, or if it introduced some new iPhone that only cost $100 unlocked. Those kinds of moves would be a significant departure from the company's current strategy, though, and Apple isn't a company that rushes to fix what isn't broken. Incremental change is normal, and Apple's refreshes generally keep its products ahead of or in step with what its competitors are doing.
