Yeah, sure. Even if what they say about the OS resource usage is true, it’s only a fraction of the total usage. A lot of the multiplatform software will use the same resources regardless of the OS. Many apps eat RAM for breakfast, doesn’t matter if it’s content creation or software development. Heck, even smartphones these days have have this much or more RAM.
I won’t argue, I just won’t buy an Apple product in the near future or probably ever at all.
