What? VHS is perfectly fine. I don't even have a color TV
This is how you sound BTW. 4k or even 1080p is objectively better than DVDs' 480p. There is no reason to still use them other than cost or being a contrarian.
Jokes aside, the fact that Wine defaults to mounting your entire drive to the fake Windows environment is a major security issue. This whole project is a very impressive engineering feat but the user experience is so bad it can have disastrous consequences.
Useless feature. Searching for any error will lead you to Microsoft's support forums, where a so-called MVP told someone with the same problem as you to run sfc /scannow then closed the thread as resolved.
No reason apart from Linux support, workshop, remote play, Steam Input, excellent customer support... You can hate Valve as a corporation all you want, but Steam is objectively the better platform, by a mile.
The NGage even used literal SD cards.
