If the iPhone didn't exist, I might very well be interested in Windows Phone. I think it's an interesting UI and has a lot going for it. However, I am VERY happy with my iPhone. There's nothing that Windows Phone does that makes me interested in looking seriously at it. A brand new product has to be an order of magnitude better than what someone is already using to make it worth the hassle of making a change. Even if I were to say that Windows Phone is the best platform out there (which I don't believe), it still wouldn't be MUCH better. For people already entrenched in the iOS world, I see nothing that Windows Phone brings to make us interested in switching. (And people who are attracted to Android are attracted to it for reasons that make Windows Phone antithetical to what they want anyway.) I just don't see who Windows Phone is that much better for. I have only one friend who uses the platform. He loves it, but the vast majority of my other friends are happy iPhone users (with a smattering of Android users in the bunch). Other than people giving up BlackBerry, it's hard to see what the legitimate target market is for Windows Phone. Most new smartphone users are going to either go with the perceive leading brand (iPhone, regardless of what others think) OR the mass market brand, Android, which they're going to see the most choices for. Microsoft's strategy isn't adding up in the current smartphone market, IMO.
