Changes in the way phones charge are coming as well. Apple is expected to adapt its MagSafe system, the magnetic power adapter currently found on MacBooks, for use with iPhones. Other manufacturers may leapfrog Apple and go straight to induction charging, which just requires laying the phone on a special surface to charge it. The Palm Pre featured induction charging in the past and it has already reappeared in some Droid phones. Smartphone cameras, too, will improve—not only in resolution but in lens quality, focus control and flash power.
