That's the whole point.
You can make your own Windows PC for much less and do all of those same things.
The point is to make Windows PC the best value option.
I'm about 99% sure that it won't be easy to use the thing for "PC purposes".
People expecting this h/w to just run your regular Windows don't really understand the model MS is pursuing.
This will likely still be a console with its own OS and own UI.
It just doesn't make any sense for MS to try and make a PC prebuilt - this market has close to negative margins as is, they won't be able to compete with huge OEMs on either price or margins.
So the h/w being closer to PC parts is fine - cuts down on R&D, allows for less platform specific optimizations needed, could potentially run a full Windows to allow running competitor's titles on the machine (for those who will care enough).
But the main s/w I'd still expect to be a console specific OS/SDKs.
Xbox Series sold 2M last year.
Likely around 1M (or less) this year given numerous stores around the world have either dropped them completely or severely reduced their stock in that time.
Who knows if there will even be a store presence for them by 2027, two years is a long time for Xbox with the current burning state it is in, and it's only going to continue getting worse, January is looming.
Shareholders will see it getting worse and continue to tear more shreds, who knows if Magnus will even be allowed to release once they're done, again, two years is a very long time.
