I would upgrade if, and only if, replacing the internal SSD is roughly as easy as it is on the current model. I upgraded my 512 to a 2TB internal drive and if they’ve made it so that replacing the internal is significantly harder or impossible, no dice. Trading in my current model (putting the original SSD back in), I effectively bring the OLED’s price down to €120 or so. That’s worth it for me considering an actual CPU / GPU upgrade is years away.
Huh, am I misremembering something? I was under the impression this update brought a function to update flatpaks / Discover store programs while still in Gaming Mode.
