One feature that would have really gilded the lily for me would be a headphone jack. Not one that works at a typical "bluetooth latency", but an instant wireless protocol like the WiiU was able to achieve.

I just accept that the occasional OS update will uninstall my few pacman programs. When that happens, I run a simple script to reinstall them.
You want to upgrade the SSD.
I upgraded to a 2tb Corsair SSD (remember when you could just buy stuff? For reasonable money?). When I copied stuff over, I started out with the Corsair in an external enclosure. The card crashed during the copy, and I think the reason why is that these cards are dramless. They borrow ram from the host, and when you're in an enclosure the "host" has no ram to give. What I had to do was put the new card in the deck, install a steamos recovery on it, put the old card in a reader, and copy in from there.
Uhh I'll leave the details of copying to everyone else, but just know that writing to an external nvme enclosure can give you a bad time.
The trackpads on the deck are nice, it's a great substitute for a mouse when you don't have a mouse. But that's all they are. Not a single game* has done anything to show off any greater potential. Binding ten keyboard keys into a dodgy ring menu is not a pleasant interface. I have never once wanted to use a trackpad as a redundant joystick input. I would like to freely pan around with one pad and point with the other - imagine that in a puzzle box game. Nothing can do this, the closest to an independent view control i've found is "bind mouse wheel up/down buttons to vertical swipes".
Heck, I would like a water filled toy game where you just press the pads to squirt rings upwards, and it feels just a little bit haptically squooshy. Nobody has done even that much to make a game feel truly at home on the Deck with the deck's controls.
The new controller looks nice, but I don't see any reason for it to replace the lowest-common-denominator xbox style controller. Especially when there are some really good xbox clones with magnetic sticks being sold for super cheap.
*okay, there's Aperture Desk Job. That hardly adds up to a game, it's basically the manual that comes with the Deck controller. I've spent more time playing the PC Jr's bios tutorial.
Artisan of Glimmith, and Under The Island. I always love me a Zeldou, but now I'm at a cooking-minigame boss and siiigh I don't wanna do that I wanna stab things.
Is Valve's update cycle really worse than what the typical Android device gets?
The future of gaming is this. Move the Memory Pak®️ around into whatever system you're currently using.

The circular scrolling thing has never worked right for me. I set it to "vertical swipe".
What I would really like is for the left pad to do panning, like a two-finger trackpad scroll. No notches, just a smooth scroll please.
Yeaah, who the heck wants to download a 20GB+ demo that gives you a 15 minute slice of a game? I'll give a bunch of 1GB demos a shot first.
Here's how I did it: take a can of electronic contact cleaner, dribble it in the switch. You have to open up the system to really get it in there (remove your SD card first). Just a drop or two, work it in, repeat.
Biden isn't president anymore. The only function of government bodies such as the SEC is to punish anyone that this president doesn't like. OpenAI is very much in favour, and even if they weren't they could afford to bribe their way out.
Heck, maybe it's really "TEU" but whoever is reporting has no idea what the EU part means so they tossed it.
