Missing features weren't Microsoft's problem with Windows Phone. You can't ship from day one with all the features whether you lead or follow.<p>Waiting until everything is there is a recipe for burning out your team and shipping 4 years later, with zero apps in your app store.<p>No, the problem is there's simply no compelling reason to own a Windows Phone.<p>iPhone integrates with Windows just fine. It's popular and feels "safe" because there's safety in numbers, and it has all the apps.<p>Android is doing well, too.<p>Microsoft had the chance to ship a phone that integrates better with Windows than any third party phone OS could, but they didn't figure out anything interesting to do with, and just shipped a normal smartphone with a trendy UI on it.<p>Look at Apple and "Coherence" now. This is the kind of shit Windows Phone should've provided for Windows computers. Instead their roadmap speaks about unifying kernels and what not. Nobody cares about your unified kernels, Microsoft. Ship features that bring visible value to users.
