I think cheap smartphones will be the most popular cheap device used for Stadia gaming since many people own a smartphone, and cheap smartphones are sometimes too slow to run HD and 3D based mobile games like Asphalt 8, and console remakes like Grand Theft Auto 3 and Final Fantasy games for Android and iOS.
People with cheap smartphones may play Stadia games when they are connected to a faster wi-fi internet connection because their smartphone is too slow to play some more intensive mobile games which need more RAM, a faster CPU, and more storage.
