Bill Mitchell does some math and sees how newspapers could subsidize purchases of iPads for long-term subscribers and perhaps even save money in the process. Newspapers spend a lot of money printing and delivering those papers and keeping subscribers. Put some of that money into a $250 coupon for an iPad, sign people up for two-year contracts, and shazam! Use those presses to print money! OK, not quite. But Mitchell argues papers would start to shift people to a new platform.
