That may sound weird to you, but my favorite devices are those that grew on me and became special.
Like the Nokia N900, my first Gameboy or my favorite X24/X60 thinkpads. They have served for years and have a place in my heart.
My steam deck became special too as it took this type of special place.
I will not abandon the poor thing to the siren of a lightly upgraded hardware.
We have still great gaming times to live.
The battery and efficiency increases are what make this worth it for me. Those are TOP of the list things for “my SD is great, but” about my 512. The increased WiFi speed, updated and very pretty screen, improved haptics etc etc, are all just icing on top for me.
Obviously if you don’t have cash to burn and already have a deck, there’s nothing make or break here. To each their own.
