Will the Samsung S4 be the First Widely Used Enterprise Android Device?

Industries (healthcare, pharma) that have higher security requirements for mobile devices the Android platform has always been a high concern.  Now that DoD has approved the Knox platform may be Android will get another consideration by these industries.
