the Steam Deck paved the way, but the idea is revolutionary if you think about it. Merge the ease of use of a console, its biggest strength, with the freedom of a PC and the possitiblity to add the OS to even more powerful hardware than the Steam Deck, typical of PC.The market is certainly undergoing change and it's a worthwhile discussion to discuss. We have children who have grown up with smartphones and tablets, streaming services etc. And having this gaming console is extremely limiting for an audience of folks who are used to playing on the go. At the same time, when a player gets more serious about gaming, they'll want to settle down into something heavier, and that's when consoles start to find their place. And after consoles, PC would be the next place to go as they continue to become more dedicated towards the hobby.
The issue is that both smart phones, tablets, and PCs are multi-purpose devices, whereas consoles are still largely designed to play games and play games only, while being locked into a similar physical space that a PC also resides.
When you try some mods in certain games, you aren't going to live without those. If MS could add emulation of MSDOS, full historic Windows compatibility since the 90s, other emulators from hardware that disappeared forever, and a native support for mods via Steam Workshop and nexusmod and the likes compatibility, stores like Epic, GoG, itch.io, humble bundle, etc etc, that could be the next step.
Make that transparent and easy to use to the most hardcore console gamers and people could use those devices for almost anything.
