If Steve built many prototypes testing different sizes with Jonny Ive, and they decided on the 10", then my money's on the 7" models being much cheaper. Until you can do one cheaper, there's no discernible reason why a 7" would gain much success in the marketplace. As in, the Fire. When it's free, it might take over the world supported by sales and advertising for the goods you can purchase on Amazon. But it's not the best size.
