“I’m still clinging to my BlackBerry,” Mr. Obama said Wednesday in an interview with CNBC and The New York Times. “They’re going to pry it out of my hands.”

“What could the “BlackBerry president” charge for his plugs of the device if he were not a public servant? More than $25 million, marketing experts say, and maybe as much as $50 million.“This would be almost the biggest endorsement deal in the history of endorsements,” said Doug Shabelman, the president of Burns Entertainment, which arranges deals between celebrities and companies.

“He’s consistently seen using it and consistently in the news arguing — and arguing with issues of national security and global welfare — how he absolutely needs this to function on a daily basis.”

… Matt Reinhard, the executive creative director of DDB Los Angeles, suggested Apple try to steal Mr. Obama away from BlackBerry as a spokesman for the iPhone.

The message could be, “It’s time for change,” Mr. Reinhard said.”
