If the MBA would have iOS, would people think that´s a good idea? I don´t think so. It´s the same thing with iPad. People are just buying the hype, because Steve said it was "magical". Yeah right!
iPad needs a much much improved (and seperate) iOS (or just OS X) than in iPhone, otherwise it´s possibilities are hugely wasted.
iOS is only for 3,5 inch devices! To try to push it in ten inch device is just sadly obvious for Apple taking the easy and lazy way out to make easy money and not care about innovation at all.
I mean come on, who (with a working brain and common sense) would want a ten inch device that has a mobile OS? Seriously! It´s a disgrace and just a plain fail from Apple. And oh, I don´t care how many units have been sold, that doesn´t make a product decesserily good.
