Windows user, so I can only speak to the Windows 10, and Android phone integration. The integration is cool, but very limited, you can see new notifications, text, email, etc.. and you can respond but you can't do anything else, like view a whole conversation. Tried answering calls but there is no noise cancellation, so you need a headset or callers can hear themselves talking.

It's almost like they have to scrape data by reading notifications, and relaying that, and can't directly interact with the mobile OS on a deeper level. Ultimately not super useful for me, hope Android Oreo provides more opportunities for greater integration.
