Economics of the new iPhone

Today Apple announced the new iPhone 5.  The key features appear to be (1) the phone is thinner and lighter, (2) the display has a much higher resolution, (3) faster performance, (4) a smaller connector and (5) enhanced camera performance, including a tool for shooting panoramic photos.  All of this for $199! 

Sales are expected to be strong, so strong that GDP could get a significant boost in the 4th quarter.  WSJ reports that an economist at J.P. Morgan Chase estimates the phone will add 0.25 to 0.5 percent to economic growth.  That's 8 million phones times $400 value added ($600 price minus $200 imported components). 

Wireless carriers sell the phones at $200 but lock in customers with two year contracts that more than make up the $400 discount.  They have reacted, WSJ reports, by adding upgrade fees and more expensive data plans. 

I am still using a three-year-old iPhone 3, so I think I will be ready for an upgrade.  Will have to think awhile about the best carrier and data plan.
