Microsoft knew Windows Phone 7 would be abandoned When Microsoft announced Windows Phone 8 two weeks ago, it did so with a notable caveat: the new mobile operating system wouldn't be coming to current Windows Phone devices. According to a new interview, the company knew early in the development of Windows Phone 7 that current Windows Phone devices would have short lifespans. 微软早於WP7发展时就知道当前的系统仅拥有很短的生命周期。 This was known as development for Windows Phone 8 was done in parallel with Windows Phone 7, since the company wanted to merge its mobile kernel with the Windows NT kernel but didn't have the necessary time. While Windows Phone 7 will be getting an overhauled start screen, it won't be compatible with applications developed for Windows Phone 8. Greg Sullivan, senior product manager for Windows Phone, told CNET UK that Microsoft knew from the beginning that Windows Phone 7 would eventually be abandoned and chose not to tell its customers. WP7与WP8是同时进行的，因为团队早就想统一为NT核心，但时间不足。 微软从一开始就知道WP7终将被废弃，但选择不告诉消费者。 Development for Windows Phone 8 even began before Windows Phone 7 was released in some ways, Sullivan said. 甚至WP8的开发早於WP7发表之前。 "The team that developed the 7.5 release actually was working in parallel with the core team that was already beginning [Windows Phone 8]," Sullivan told the technology site. "In fact some of that work was already initiated before Windows Phone 7 was even available – so this goes back a little bit." WP7.5开发团队与WP8核心团队同时进行，某些部分甚至再WP7完成前就已启动 Sullivan told CNET UK that unifying Microsoft's Windows kernel with its Windows Phone kernel was "always the plan" and called the lack of compatibility between Windows Phone 7 and Windows Phone 8 a "generational shift." He then went on to add that Microsoft doesn't expect a similar "generational shift" in the foreseeable future because of the design of the new architecture. Windows Phone 7 devices will continue to receive support and work with Microsoft's online services, such as SkyDrive and Xbox Live, even though they won't be as tightly integrated with Microsoft's upcoming Windows 8 operating system as Windows Phone 8 devices will be. 更换核心一直是微软的计画，因为不想在可预见的将来再做一次这样核心更换 尽管无法与Win8高度整合，WP7仍将接受如skydrive与XBOX LIVE等服务 According to Sullivan, Microsoft chose to launch Windows Phone 7 knowing its limited timeframe because it had to compete against Android and iOS immediately. "It was important for us to establish this new approach in user experience and begin to build the developer ecosystem," Sullivan said. "Those are necessary but not sufficient steps to establish a new platform and we didn't want to wait until [we were able to launch Windows Phone 8] to begin that because we're maintaining those core characteristics of the platform." WP7的推出是为了立即投入与阿婆及估狗的竞争，不能等到WP8平台出来再做 新闻来源： http://www.neowin.net/news/microsoft-knew-windows-phone-7-was-dead-on-arrival 随便附上大意，这里有一篇更完整的 http://is.gd/IWlcSe --
