Unfortunately, even a huge speed increase isn't going to help Apple sell more iPads because almost no consumer cares about having more speed. All consumers want are cheaper iPads or tablets. Android tablet market share will continue to grow and Apple's iPad market share will shrink that much faster because of the higher sales cost. Apple's goal to provide the best tablets to consumers will remain intact but Apple's bottom line in terms of revenue will drop. Apple's consumer goals are basically a hindrance to the company's share price.
It's really a shame the tech industry doesn't acknowledge how good Apple tablets are. I'm sure the pundits are already yawning when they see the iPad Air, saying that it's just a faster, thinner, lighter tablet and complain that Apple has totally lost all sense of innovation and is overpricing itself into oblivion. Meanwhile, all the Android tablet vendors will be lowering the prices of their tablets and Wall Street will congratulate them for putting Apple out of business.
