The fact that for less than $100 you could get a refurbished OLED model with the same amount of storage as highest storage LCD model (512GB) is insane. If the OLED model was out and had verified refurbished models on sale back when I bought my deck, I would have absolutely done it. Not upgrading any time soon if I can help it since I love my deck, but damn it would've been cool to have the OLED model.
Unfortunately Deck 2 timing is unknown right right now, haven't had any leaks suggesting that we'll be getting it soon. We know Valve is releasing SteamOS for more devices, starting with Lenovo handhelds, but it's not clear if we'll see SteamOS for any non-handhelds in the immediate future.
We are getting a new Steam Controller soon, which I'm hyped about.
