I've been using GeForce Now quite a bit to play games that do not run on my laptop. The required internet speed is probably out of reach for most non-urbanites at the moment, but the concept does not really require a Native App, since it is basically video streaming with interactivity, and could probably easily move to the browser in the future.

Cloud gaming is one of the technologies I'm quite unsure about, it could become the de-facto standard in the coming decade, or it could remain a niche, all depending on consumer preferences and network infrastructure.
