Samsung already offers virtualizations and containerization via KNOX for you to run apps you don't fully trust safely without disk and shared memory access, on their midrange phones. Surely Apple being wealthier and selling higher priced phones, with even more powerful SoCs can definitely offer similar security functionality for non-IOS appstores. The reason they aren't is they want to push the security boogieman scaremongering to defend their monopoly.
