In all honesty mate, you would be better off saving that money towards an actual PC. In my humble opinion of course.
What you think you are going to gain is never going to justify the cost. Steam is great and all that, but with this thing you are still going to only end up playing games you can on the switch or gamepass at some point. The actual reason to have a PC and the likes of steam will never work on this.
I'm not against it, I'd love a contender and as you all know, I buy every hardware there is. This though, meh. Like the Steam controller, I'm not even in the slightest bit impressed. I don't get the tingles that I must buy.
And I still own my Atari Jaguar
