I think Apple has alienated enough people that the tide will swing against them pretty fast and hard. Structuring their App Store policies to make it more difficult for the likes of Amazon to sell products to Apple customers was perhaps the last straw...
Beyond sellers and developers, perhaps more "regular" customers will now start to realize that Apple intentionally limits their choices. This is what finally drove me to sell my iPad.
The weird thing is, lot of Apple customers either are OK with the limitations, or they are not aware that they are being limited. This doesn't make sense, given we now live in a world that is all about choice. I think Apple has somehow found a way to appeal to people's need for order and "neatness," masking the loss of choice. Also, they got into the tablet game first and got a strong head start.
So, I think the big question is, can Android continue to deepen its multi-faceted possibilities, and yet still present a friendly model for "regular" customers?
Getting Amazon on board, using Amazon's familiar site structure that everyone is used to, may be a huge step in this game.
Thanks,
