To everybody dismissing this because they already have a steam deck: do you not think more SteamOS devices is a good thing for Linux/Proton gaming? This benefits Steam Deck owners too.
I have a deck and would 100% buy a Deck 2 assuming the price isn't crazy, but I absolutely want more SteamOS offerings from other companies too.
Sure, as long as it’s not made by ASUS. I used to always buy ASUS. My last gaming rig had an ASUS motherboard and GPU. Nowadays, I’m not interested in ever buying anything from them again after hearing about their RMA controversy. I need to know that if I get a component that’s DoA or fails under warranty, that the company that makes it has my back.
As for the "poor Linux support" - that's exactly what people are talking about reversing. If it officially supported SteamOS and had up-streamed drivers in the kernel, it wouldn't have poor Linux support.
As for the other stuff, sure, perhaps you're right. But nobody is saying you have to buy it. It's still a benefit to you as a SD user to have more people using SteamOS.
