While it will certainly suit some people, the Oculus Go seems a bit of a gimmick at that price. For £200 you can get a barely used WMR headset from ebay, which will run SteamVR games and has 2 controllers. It's also got a great resolution, but admittedly the optics will be worse than the Go.
I just couldn't justify buying the Go for that price, given that it's so limited in purpose. It seems like something that will be rarely used after the first few weeks.
