Talk of the iPad Mini cannibalizing sales from the full-sized iPad has been around since before the iPad Mini even arrived. But any notion that Apple was worried about cannibalization was squashed by CEO Tim Cook. "If we don't cannibalize it, someone else will," Cook said, adding, "There's a lot more of the PC market to cannibalize."
The worry that the iPad Mini will take a bite out of its bigger brother has always been short sighted. If the iPad Mini ate one full-sized iPad sale for every 3 Minis sold, the net result would still be more profit for Apple. They'd also have three users to sell apps, music, movies and books to instead of just one.
Microsoft Surface Pro Sells Out
If you look at the Surface Pro as more of an ultrabook than a tablet, which is a fair assessment, you can see how the PC market is evolving to become more tablet-friendly, in essence, killing itself before someone else can kill it. And Microsoft's newest tablet is only one example of how PC manufacturers are looking to tablets for ideas on where to take the market.
But the Surface Pro selling out might be more due to Microsoft's limited supply than the people's demand, with some media outlets reporting on complaints that Microsoft sent too few units to retail stores.
