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.
Im more than happy with my steam deck, If I ever decide to give it to my son or sell it then I may upgrade but cant see that happening for a few years yet.
