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 think it’s a big difference compared to the SWOLED. That really was for the most part just the new screen. Which was amazing but would really be all your upgrading for.
Valve actually nailed this with fixing a lot of issues people had by adding more battery life a better refresh rate etc.
Now sure it’s not fully worth it if you already have one as there not huge improvements. But they are good ones especially the screen.
I want to sell mine and buy the OLED version. Just not sure what the resell market is like for Steam Deck. I feel it’s a bit harder or a sell than the Switch.
