Sales are down this quarter because Apple has shifted from releasing new iPads in spring to releasing new iPads in the fall. It's kind of silly to attribute it to the current crop of Android tablets which are still pursuing the losing strategy of slashing prices to stay afloat. No competitor has come anywhere close to touching the iPad's dominance, so all the developer attention in the tablet space is focused on iPads. Here, look:

The evidence seems to suggest that people who do buy other tablets tend to regret their decision. But the truth is, no one has solid facts about what happens to all those tablets after they're sold: they just seem to be invisible in real-world usage.

Wait, am I reading this right? 10 to 25 million iPads sold in THREE MONTHS? Ain't this INSANE?

Great news. Ipads sucked, its about time idrones figured this out.

that is only us and canada. everyone i know with a tablet uses them. Only 1 has an ipad.

Edit: it gets it data only through who sees their ads. for all we know more of their ads are on apple products than android, especially since android is run by google, another advertising company. do you have any other usage info? this doesn't seem to accurate or usefull knowing how they get their info.

1. The economy is bad

2. Everyone already owns an iPad/iPhone, so upgrades are a luxury

Apple doesn't actually care though. It's not a console war. They'd rather have lower volume and retain their margins. 

A few of the major Android players are already in financial trouble from the pricing.

True, Apple will always maintain their extreme margins. But, the Android players are not in trouble... they're just all being beaten by Samsung.

The others all have YOY increases, just not as big as Samsung. Except for maybe HTC I guess, I don't think I ever really read positive financial news for them. But, that was largely to their diluted product pool. Now that they've stopped the "Droid" brand nonsense and focused on at least one high quality phone, they should turn around.

But ASUS, LG, Samsung, Google/Moto, etc are all doing very, very well.

I guess it hurts to have a new model every six months.

I think it's funny how Apple just seems to be so willing to let other companies use common sense to steal all of their customers while they get regulated to a small minority. Happened with PCs, happened with smartphones, and now it's happening with tablets.

they have used the same strategy for all three. They will get the same result. Apple wants a locked down OS, locked down store, and locked down hardware. it limits their abilty to try new features(since they only have 1 model they cant be too risky on it), they also have less of a source for innovation since they are 1 company while android (and windows) has many manufactures bringing many new ideas to the table. But as long as they make oney on every sale their market share doesn't matter. AS long as they have enough apps their market share doesnt really matter. I think the real fight will be between windows and android. we shall see
