Your second wish already exists. It's made by a company called nexdock. I think you can plug your phone in or run it over bluetooth/WiFi.

Something that plugs into my PC where I can plug my headphones into it, and it creates two virtual audio devices that I can fade between by turning a knob.

This way I can independently adjust the volume of my game and YouTube, like being able to turn one or the other down or off independently of each other without having to tab out or adjust in-game settings.

a note 9 with postmarketos/android dual-booting and a bigger fingerprint sensor.

They figured out the perfect phone with the note 9 and every samsung has been worse in some way since.

A modern Steam Machine console/PC. I just got the Steam Deck and I love it, but it's roughly PS4 power. I want a PS6 with the same or better SteamOS build that the Steam Deck has. I want simple modular upgradability. I want it to come with a controller that's basically the Steam Deck without the screen, but with the comfort of a dualsense. I want to have a device that can replace both my PS5 and my laptop from 2015. I want the freedom and multitasking of PC with the standardization and comfort of console, updated to this decade.

A robotic AI pet. Like a small dog or cat. Preferable able to read my body language and react to it. In a low price range that I can afford. Everything on the market is too dumb, too expensive, too hard to program and there is non that can read body language.

Brain implant that puts me in any world other than this one. Preferably with cute anime girls involved.

An Android phone with a decent processor, one decent camera on the back (no front facing), a 1440p 5.5" OLED screen, a headphone jack, and long term update support for a reasonable price.

A machine that perfectly dispenses things: The perfect amount of cereal + milk in a bowl The perfect about of squash and water The perfect amount of soap/shampoo The perfect amount of moisturizer

Your second idea has existed in a few different forms, I think Samsung was the last to try it but I can't remember anything about the product

A proper glass desk/table like the one in Oblivion. And proper full sized glass whiteboard like in Hunger Games

A Microsoft Duo phone that isn't shit

A VR headset that is lightweight, has a decent battery, and has controls dictated by gesture and eye focus (so I can finally start sketching out 3D geometric objects and exploring a fun idea I had for a model of hyperbolic space)

As I stare at the mess of charging cables and USB stuff on my floor, I look forward to when we will charge things wireless-ly.

An app on my phone so that when I point my camera at a street, building, landscape, the app will overly identifying info.

A laptop without a screen, instead a projected holographic screen with tactile feedback.

When my laptop is far away, across the room, I want a tiny, moldable item in my hand. Just press, next song. Not a wireless mouse, something way tinier, can adapt to tiny finger movements.

A flexible material that can be molded into shape, locked into place. So many uses.

I'd like to hold my phone, and in a quick gesture "throw" data to my laptop.

A single remote that turns on my PC and TV
