Motorola may have once said that it was "open" to developingWindows Phone 7 devices, but it looks like that possibility is now a whole lot less likely than it already was. Speaking at Mobile World Congress this week, Motorola's corporate vice president of software and services product management, Christy Wyatt, said that while she would never say never, she doesn't envision Motorola using Microsoft's OS, and added that "it's not something we're entertaining now." Wyatt went on to say that "there were a bunch of things that we believed about Microsoft that ended up not being true, mostly about what functionality it would have in what period of time," and further explained that Motorola is looking for "an opportunity to create unique value," and it doesn't feel it can do that on a "closed platform" like Windows Phone 7. Obviously, it does feel like it can create unique value with Android, and Wyatt dismissed concerns about a potential duopoly between Android and Apple, saying that "It could be a duopoly on platforms but I'm not sure why having another OS is a good or bad thing." Incidentally, she also said that the upgrade process for Motorola's Android phones has "humbled" the company a bit, and she promises improvements in the future, noting that "we were better with Froyo then with Éclair and we'll be even better with Gingerbread."
