I will definitely give it a shot, but not until I can do so without a big, upfront purchase. The idea of game streaming is very attractive to me. I'm not sure that the tech is really ready yet though. I definitely want to check it out though.
For what it's worth, I'm more.excited about MS' streaming offerings. Not only does XCloud sound better to me, but MS is a much bigger player in both cloud computing and gaming. So, they should be better positioned to deliver a good service.
Specwise stadia wins, xcloud runs xbox one s hardware, a tester posted a video showing it on a phone, played Gears 5, the latency is unnoticeable, but the stream was just 720P/30FPS. The free version of Stadia will offer 1080p@60FPS games.
