Well if Apple could ease up on their 84% profit margin all the time (yes, I'm exaggerating so calm down) then they could make a $200 non-contract iPhone with a FEW missing features. Make it:
1)Small 4GB storage
2)No GPS
You may not be aware, but Apple is a public company with a mandate for profit maximization. Easing up on profit margin might make tree huggers and consumers happy, but it would make the people who own Apple very unhappy, which is why it's not going to happen.
But more likely Apple should just concentrate on a $99 iPhone WITH a contract to attract people who aren't going to spend a lot of money for a bleeping cell phone...this rumor has been reported a few times in Newsweek/WSJ type publications. They've been selling 8GB $49 3GS iPhones for awhile now...you telling me they can't make a version 4 or 5 for $99?!
Of course they CAN. But it would be less profitable so they WON'T! They don't need to. They can already sell as many iPhone4s as they can make for $600 each to carriers around the world. WHY would they spend precious manufacturing capacity to make LESS money?
