After the most recent quarter Apple CFO Peter Oppenheimer was proud to let us all know that there are now 365 million iOS devices "in play," with over 50 million sold just in Q2. With the iPhone now available in 100 countries on 230 carriers and the new iPad shipping in over 40 countries, the continued growth isn't much of a surprise. Obviously, as the number of devices in the hands of users increases, so does the number of apps, and in this quarter the iTunes app store topped 600,000 apps -- including over 200,000 specifically designed for the iPad. The iPad in particular was singled out as being a driver for growth. Tim Cook said that 67 million iPads have been sold since the first model debuted. By contrast, he claims it took 24 years to sell that many Macs. Oppenheimer said that the education market was increasingly turning to the tablet, purchasing them by a margin of almost two-to-one over Macs. The San Diego school district in particular ordered 10,000 this quarter and has plans to purchase 15,000 more. Even the government is getting in on the action, with the air force using them as flight guides. For more details from Cupertino's earnings call check out our live blog.
