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 don’t need it. I already have a friend who wants to buy my old deck, so I lose just about nothing in upgrading. I want it, I’m financially stable, so I’m getting it.
It’s my money, and I don’t need to be told how to spend it. Thank you.
