If you have the income and want it, go for it.
Between parts for my race car, equipment for my astronomy hobby, my gun budget as a firearms enthusiast, and my ever growing determination to cover my body in tattoos, I can’t be going and upgrading every piece of video game tech as it comes out.
I chased that for awhile with PC building, put $5,000 into a machine with every top dollar component that was comercially available… That lasted all of two months before better stuff started hitting the market at a fraction of the price. These days I don’t care so much, I can wait and upgrade every few generations.
I will forever be triggered that the 1200p screen is called Deck HD and not Deck FHD. The standard 800p screen of the Steam Deck is already considered “high definition”.
