Nokia's (NYSE:NOK) rumored "Sirius" tablet was expected to launch as early as this month, just as Microsoft (NASDAQ:MSFT) is likely preparing to launch two new Surface models in the near term. That would potentially mean Microsoft effectively has three tablets about to be launched.

Meanwhile, Microsoft runs a big risk of alienating other OEMs that it now competes with directly. This risk could even potentially bleed into other markets that matter more to Microsoft, since many of these manufacturers also make PCs and other Windows devices.

In the following video, Erin Kennedy discusses the implications of Microsoft's deal with Nokia with Evan Niu, CFA, and Eric Bleeker, CFA.
