Now you're just framing the debate in a biased way so that nothing can ever beat Apple.1) Tablets are not a hard or even important problem
2) Tables are used for media consumption, such as video or books
Does this thing come with iTunes? With all the music and movies you've already purchased?
Does it come with Amazon's book library? With all you can read free deals?
Does it play iPhone games? Since they get everything first and guaranteed to worth silk-smooth?
If not, it doesn't matter and is not a contender to anything.
As I say above - of course people who want to run IOS (because of the games, whatever) won't be interested in this. You are evidently one of those people.
But not everyone is like that. The fact that Android outsells IOS on smartphones (and even Symbian outsold IOS on phones during its lifetime) is evidence of that. Indeed, most people use computers for media and Internet and games rather than creating content, but Windows is still doing fine.
One could just as well change the argument around and say an Ipad or Iphone is not a contender to anything Android, because it doesn't have, e.g., Google Maps with free satnav (or whatever else) (I consider free satnav as standard to be a killer app, and have enjoyed using on both Nokia and Android).
There are other ways to play music than Itunes (any many of us prefer the other ways). For Amazon, the Kindle Fire presumably is the best supported here - and Amazon does have an Android app. No it can't run Iphone games, just as an Ipad can't run Android games. It is indeed depressing that Iphone still gets catered for first and foremost in apps, despite it never having the largest market share, but there's still more than enough games to choose from - Google Play is flooded with apps. (With the dominance of Android, it may well be that the situation in app support reverses sooner or later - will you change your opinion then, and switch to Android?)
Now yes, you'll probably reply and argue what's so wonderful about Itunes and Iphone games and so on, but that's missing the point - nothing you say will change my mind. My point is that many people have different opinions about what is best, or why they want to buy something, and not everyone has the same view as you. It is wrong to say that an Android device has no chance because it can't run Iphone games, and the overwhelming success of Android smartphones (and Symbian before that) has already shown this. There is room for more than one platform in a market - just as people still happily buy OS X machines, despite most people running Windows, for example.
