I will start off by saying I am not a fan of Windows Mobile 7, at all. But I am very excited that it hit the market. This is pretty obvious to everyone but the more OSes we have running on stable hardware the better! More competition, more choice, the end results is a better product to whatever fits your needs. WM7 seems a lot like a demo to me, but it might have potential down the road. iOS really hasn't come that far, they have the iPhone, iPad, iPod Touch. Android looks to be great, pretty flexible, Android is running in many phones, tablets, and even my TV has Android (Sony Google TV). When Android was first released it was a neat platform, but is has grown by leaps and bounds very quickly. It is possible that might happen with WM7 (Microsoft has been wanting to do this for a while, look at what they tried to do with UMPC's) I think the idea of iOS is going to be moving out soon and we will see a newer more "full computer like" version of Android moving in. And hopefully WM7 will compete, and I would love if Nokia joined the fight - but I am not holding my breath. What do you all think?
