I just installed it and according to Google I am the proud owner of a new Google Pixel XL device. lol.. I installed some apps from the google play store and they're running fine.
Now...here's the cool part.. I "right clicked" on my .apk and it allowed me to install it into the bluestacks app and it ran fine. 🙂 You can't switch the device it's emulating, but it's another useful tool to test your app. Also kind of cool to run all those google store apps on your desktop.
My dev machine is a Windows 7 system so I have no idea how it will work under another os.
