That's good to know. One of the things that pushed me completely off Android was discovering how few even Microsoft apps I could use without Play Services' malware being installed as well.

And it's very likely Google will find ways to retaliate against Microsoft for working with the Amazon Appstore here. They are pretty aggressive against forks. Honestly, I would suspect the next Duo won't be able to run Play Services, because Microsoft dared to work with a competing Android app store.

Wouldn't that Duo2 then be the perfect point for Kindle and Surface to join forces?

Just speculating - I know nothing about Android support at Microsoft.
