I made this exact mistake when the Switch OLED came out. I got caught up in hype, I bought the new one, and slowly it dawned on me that I just spent 300 extra dollars for exactly the same machine I already had, and a screen that, as good as it was, was NOT worth that 300 dollars.
If you don’t own a Steam deck, then go nuts! Do what you want.
If you already own a Steam Deck, you already own everything you actually wanted a Steam deck for. An OLED screen is not going to make the games you already play somehow magically better. You’re fine. Chill out
I bought the switch OLED, due to my kids using my OG switch some times, and it made a lot of difference to me, not becuse of the color only but the screen size. The stram deck screen size doesn’t look too of a big jump. But that plus more battery and better thermals are super attractive to me. Specially because I always target low settings for 40 fps and 10W TDP just because of the noise and battery life. I could still do the same but with better graphical settings. The problem is that now the used market is saturated…
