By contrast, most iOS and Android buyers just swapped their smartphones. That's significant, because unlike the global mobile phone market that saw Q1 smartphone sales outpace feature phones for the first time ever, domestically, there are still more old-school units. If the trend to upgrade from feature to smartphones continues, Microsoft should benefit. It's not difficult to find analyst and tech gurus bemoaning Windows 8. That's the nature of the IT beast. But as Kantar's data highlights, Microsoft's new OS isn't going away any time soon, and given a few more quarters like this one, will start making some real noise in the smartphone and mobile computing markets. On top of Microsoft's recently announced fiscal Q3, this latest news should have long-term investors feeling awfully good. With the release of its own tablet, along with its Windows 8 operating system, Microsoft is looking to make a splash in the booming mobile computing market.
