the change will be that you are given access (via the new and even more crappy windows store that will connect to amazon app store) to a couple hundred thousand android apps compared to access to all the million android apps that are available if you use a real android phone or an emulator or virtual machine on windows or mac (that connect via the normal google store)
Nothing like this, and native support takes it to another level totally. I really see the merit to Nadellaās concept of Windows being the center of your tech world, running Windows apps and browser apps, and also PWAs and Android apps. By far the most flexible system out there.
