"A grey phone could be shrink-wrapped and something you could buy at your local convenience store," said Eremenko. "Your fire up your grey phone, run the Ara configurator and start purchasing modules in the marketplace."
Module prices will be left to companies that produce them with the expectation that competition will drive down prices. The standard size and interface used by the modules could also spark a second-hand market, but that could take months or years to get off the ground.
Future developer events are planned, said Eremenko. At the next of those, Eremenko hopes his phone will work.
"I wish I could make a phone call from stage, have my Steve Jobs moment, but we'll have to save that for a future developer conference."
