Or more likely, the superior, extra-cost cabinet shielding. The distortion field is needed when you write the check.protected by the reality distortion field!
There is another trend in PCs. People recording entertainment content (trust me, the way I do it, it's "content" not music) on Windows machines discover that they're not general purpose computers any more. Microsoft threw it's lot in with Corporate Interests and the machines come out of the shrink wrap set for conferencing, communications, and collaboration, not recording arpeggios.
It would appear that external sound devices (USB3??) are normal, not the expensive, exotic exception. You could always get an internal "Sound Card" that had Superior Shielding, XLR connectors and good microphone amplifiers. Few people bought them, but you could. Now, you can't.
Sound On Sound magazine regularly does equipment reviews and the local news stand carries it. I buy the ones that review the stuff I'm interested in. I think the latest one I have was microphone amplifiers.
