Why would it decimate the Windows market? From my experience, there's a strong correlation between iPhone and Mac usage.
Looking at the stats, the Win:Mac ratio is 4:1 but Android:iPhone only 2:1 so it might hurt Windows. But if iPhone users are more likely to use Mac or don't use computers much already, then expanding iPhone capabilities would cannibalize Apple business.
