The big news out of Barcelona this week was Microsoft’s announcement of Windows Phone 7 Series, the heir to Windows Mobile and Microsoft’s platform of choice to evolve their mobile strategy. With a UI that’s looks very familiar to users of the Zune HD, I think Microsoft has done an excellent job re-inventing their mobile strategy. It’s clear they are no longer playing in this market, they’re playing to win. It’s also clear that this year will be a major inflection point for mobile and Microsoft has gotten off to a good start, much better than what we’ve heard so far this week. The key will be execution and delivery on the things they’ve shown us this week. You’d think that would be enough for most folks, but it’s clearly not. It seems there are some out there that are still looking for more.
