That seems to reflect data on Google Insight's macro trends - that Android is on war path to crush iphone. Having said that for the not so tech savy (most people!?), iphone has already staked a position in peoples minds and I doubt will be dislodged that easily... Let's face it - do I want to cancel my contract with Iphone for an ambiguous upgrade? I spent a year personalizing 50 apps which help me shop, swim, eat, measure, socialize, learn, conceptualize and collect. My brain can't possibly hack any more.
Factor in Jobs' exit aswell, the big one and I probably agree - Google will almost certainly swallow Apple.
