Shelving the question of Adobe's strategy or competence for a moment, I think this review is indicative of Apple's competitive advantage. Assuming Adobe had infinite time and resources, could they make Flash run well for all content on every mobile device? Of course not, they are hamstrung from legacy support as well as variances in hardware and software stacks they have to deal with. But just like Microsoft they are…
MS/Adobe are unlikely to fall below 60% (especially since this is not a zero-sum game.)
