A grain of salt now, a mountain later. I'm not saying the numbers are legit, just that if they are it's only a matter of time before Apple is enveloped by the Android hoard.

That is the assertion of the title, but the body of the article (correct me if I'm wrong) refers to total units, not noting that (A) it took Amazon, Samsung, Google, HP, ASUS, and all other companies that make Android tablets lumped together to out-sell essentially a single product[1] from Apple, (B) most of those devices were low-price low-profit-margin units as contrasted with Apple making some 50% profit off each sale, and (C) how many of those units were relegated to minor usage (or disused entirely in short order) for minor purposes (video player, occasional games) vs "heavy use" (broadly speaking; see other comment about actual network traffic).

My snide "it's Friday and this coffee was too strong" side envisions comparison of the aggregated productivity & vitality of our intrepid hero against waves of zombies.

They guessed at the revenues, not the profits. Apart from Apple and Samsung, no one is making money selling tablets.
