I'd love to know where all these other tablets are being sold. I was just on a flight to San Diego and I saw a number of people using tablets in the airport and on the plane and they were all iPads.
The sales figures cover a single quarter. There will be close to a hundred million iPads sold between 2010 and 2012 so they're still the overwhelming majority of tablets in use but the competition is ramping up in a growing market.
