"If so, this might be a situation where an under-served market allowed an agile opponent to bust into a market firmly held by a single dominant incumbent!" This is silly. The reason Android sells more tablets, globally, is the same reason Android sells many more phones: Apple doesn't compete in the bottom of the market. Apple makes tablets that sell for $329 to $929. If you limited yourself to that market you'd find that Apple sells the overwhelming majority of such tablets. If OTOH you limited your comparison to "tablets under $300" (an actual "hot link" at Amazon) you'll find that zero of these tablets are from Apple and hence Apple's market share for this part of the tablet market is a (perhaps shocking) 0%. You'd find a few windows and linux tablets but mostly 95%+ Android tablets (including forks). This does not mean Apple has been outfoxed by a more agile opponent. Apple presumably could ship a lower quality tablet at every price point from $50 to $250 with their eyes closed.
