I think this is a big misunderstanding of Apple's customer base for these systems.
These GPUs are optimized for rendering tasks, not for FPS count for gaming.
> Very few games are optimized for it...Hopefully, these drawbacks will change if enough people buy these M1 machines, but there is no guarantee.
There is a guarantee, and that guarantee is hardware-level compatibility with iOS and iPad platforms.
There's a whole section of the Mac App Store called "Great iPhone and iPad Games for Mac with M1"
iOS and iPad probably represent a larger gaming installed base and revenue than PC and consoles combined.
Opinions may vary, but personally I think that being able to run Windows on your Mac is far, far down on the list on reasons to purchase a Mac. It was a very handy tool to have especially 15 years ago when the Mac didn't have as much commercial support, but in 2021 I don't think a lot of potential Mac customers really care about Windows compatibility.
A small market indeed. Very few people need this powerful of a computer. Most people browse the internet, use a word processor, and some play demanding video games. Video games is the only category that remotely approaches the need for these powerful machines by John Q Public.
