According to Techcrunch via Gizmodo, Microsoft is planning to drop some serious cash on its Windows Phone 7 venture- to the tune of half a billion. The cynical response to that is, well, of course, that’s how Microsoft tries to solve all of its problems…by just throwing money at them. But it’s hard to ignore that much scratch when you consider that Verizon, Motorola, and Google – combined – spent merely $100 million (for those of you terrible at math that’s 1/5 as much) on its Droid crusade to secure some market share away from iPhone. With Microsoft lagging far behind everyone in the mobile market right now, a little extra cash wouldn’t hurt, especially with the good buzz surrounding Windows Phone 7. As a former WinMo slave/addict, I’m at least curious to see one of these new devices in action, although I can’t imagine abandoning my new home at Google (especially when my Nexus One is capable of being this sophisticated and powerful). Windows Phone 7 is make or break for Microsoft’s dwindling mobile market share, and I think the loose wallet is indicative of just how important this is for morale.
