> I wonder, why is it physically painful for some Apple owners

This wasn't necessary. I was just pointing out that 8GB hardware is not the full story. It's also true with windows, as you correctly point out. If you're coming from a slow SSD, or even Linux (it's a relatively new feature to have on by default) you might be pleasantly surprised.

Also, I'm an Apple owner and I have no problem saying it's not enough for anyone on this website. I tried it for a few years as my "second screen" computer, and would bump against it all the time, with glorious screeching as the audio skipped. But, I'm also a developer/power user.

The majority of people aren't power users.and that's the target audience for this. Clearly.

8GB has been completely fine for every non power user I know. Again, the majority of people do everything within a browser, maybe play some music/video at the same time, maybe open an office type app. It's completely acceptable for that, and that should not surprise you, as someone who has an understanding of memory usage and paging, and high bandwidth SSDs, in the slightest.
