According to a lot of devs and CTOs I've met, Google and Apple can't do anything wrong while Microsoft can't do anything right.
I can't risk having a corporate rollout/demo/pilot fail because some developer made the Googlebot pissy and got everything they're associated with banned.
I trust Microsoft way more than Google at this point. That says something.
But that is way different than Embrace, Extend, Extinguish from MS. I would not trade, say, Chrome for the world of IE. the tension between Google and Apple is far healthier for developers and consumers.
