Paul Thurrott's SuperSite for Windows posted an article about how Microsoft can fix Windows Phone in 2011

I've made no attempt to hide my love for Windows Phone 7, Microsoft's innovative and trend-setting new OS for smart phones. In fact, I wrote the book. But Windows Phone, like any other 1.0 product, is as full of holes as your typical Swiss cheese. For that reason, and because high-quality competitors like the Apple iPhone and Google Android are getting better all the time as well, Microsoft needs to move quickly in the next year to address the missing features and continue to ensure that, from a high level, Windows Phone continues to outshine the competition.

Here are some of the ways in which I'd fix Windows Phone in 2011. Note that most of these are high-level, big box feature requests, not picky little issues with individual buttons or screens. There are a million tiny ways in which Microsoft could change Windows Phone--multiple calendar support, a camera that retains custom settings, and so on. Those are all as obvious as they are necessary. But these are the big ones.
