This is aimed I suppose for Android exclusive apps like games but for apps like WhatsApp for example it doesn't make sense since you have WhatsApp Web and WhatsApp for Windows PC.
Android apps are made mainly for Android smartphones and they are meant to bring mobile experience to the users. You won't be using Android jogging apps and be running together with your PC in the pocket like you can with your Android smartphone.
WhatsApp (even the Web/"Windows" versions) don't work without a smartphone though, do they?
I know I'm in a minority here, but I don't own a smartphone but still have to use WA to stay in contact with some people. I have to run it using the BlueStacks emulator on my PC. I'd love to replace that with native support for Android.
