I must say Windows Phone has been a poor venture for Microsoft. Ok Windows Phone 7 didn't meet expectations, it came out late and after what seemed to be an initial launch period buzz nobody cared about it anymore. I am seeing the same thing with windows phone 8, buzz at the start of the launch, and then nothing.
I like the OS, it's better than Android and iOS, but for some reason Microsoft can't take off with it. I am sure Microsoft is also perplexed by it. Apps won't come until this gains popularity but it hasn't. Microsoft doesn't have the pull that Google and Apple does.
