Living in Japan. Xbox reward (available in Japan) turned MS Reward and MS Reward is available in Japan (and Taiwan too) now.
* China is a whole different story, but currently, I think they are doing co-op dev with Chinese tech firms I think. No one can operate in China from outside China. (I'm in the game industry)

tbh... I never feel like I want to talk to my phone or PC, esp in the office. But there's a circle button on Win10's TaskBar and you can talk to Cortana through it I think (I never did / tried).
* But I do believe AI (not Cortana, Cortana is just one of the skins) is very important in SW development.
Living on the internet for years... I don't think MS's keen about selling HW (Sony does cause it's their bread and butter). Surface for example... it's more like a beacon, a direction, a premium product that can be displayed in the retails, to show people Windows can be cool and sleek. Like Nexus vs OEMs.
But I agree, HW aside, MS should talk to more gov, iron out whatever regulations and try to bring their SW services to more countries. I live in Japan but I use English as my default for everything and everything just works. And unlink Google, thank god MS store doesn't have a region lock (yet).
