I have a PC that comes with a 300w charger. I can charge off a 100w GaN charger so long as my power profile is on battery saver. I’d expect the same for OP.
I’m concerned with the state of consolidation in the gaming space (and just about every other market, I might add) but I also find it hard to argue they’re a monopoly. They’re number three in the console space and thanks to Proton Microsoft’s de facto stranglehold on PC gaming OS’s is weaker than ever. I could see cloud gaming being a problem in the future but it’s such a nascent market who knows what will happen there.
I’m sure they’re waiting for the price tag of a device with the features you describe to be more in line with current steam deck prices before doing that. They probably don’t want to annoy early adopters either.
I booted up 2.0 Sunday night and had a nice laugh when I called my car to my location. It wedged itself under a car in traffic and threw that car violently into pedestrians on the sidewalk. The jank is still there, it’s just at a tolerable level.
