I think WM7 will be at least a modest success for Microsoft. The Android handset makers are pushing the platform in a weird direction. Larger handsets & more software complexity. I think there's probably a lot of people out there who don't want either an iPhone or an Android device for various reasons. Most of them are probably RIM users today due to the simplicity of BBOS. WM7 will be a legitimate option for them. I could see WM7 having a 10-20% market share within a few years.
