Samsung's Galaxy Note 8 has joined a handful of other phones at, of all places, the Microsoft Store. Both the online store and brick-and-mortar locations have the handsets, both unlocked and carrier-branded; today, they're $780, with a regular price of $930.

The Note 8 joins the Galaxy 8 and 8+ as well as Razer smartphone; Microsoft is selling all four Android handsets, alongside three Windows Phone devices (including the HP Elite x3, newly available to Verizon). Why is Microsoft selling Android handsets? Well, the company says, you can run Microsoft Launcher, a home screen/app launcher replacement for Android, along with all of Microsoft's other Android apps, such as Office, Cortana, and Skype.
