There isn’t official pricing nor reliable sources out there so I’m going by rumors.
With your calculation you have to keep in mind that the Switch 2 cards have to somewhat match microSD Express speeds, so a more accurate comparison would be these, but they aren’t available in 64 GB sizes.
All I’ve heard is that they’re expensive and with the larger sizes often required for Switch 2 games it’s an even bigger problem than with Switch (1). These key cards exist for a reason. And I’d bet Nintendo takes a margin on these instead of only requiring the publisher to cover the manufacturing costs.
Tumbleweed. Rolling release with automated testing (openQA), snapper properly setup out of the box.
Honestly the entire openSUSE ecosystem. Tumbleweed on my main PC that often has some of the latest hardware, Slowroll on my (Framework) laptop because it’s rolling but slower (monthly feature updates, only fixes in-between), and Leap for servers where stability (as in version/compatibility stability, not “it doesn’t crash” stability) is appreciated.
openSUSE also comes in atomic flavors for those interested. And it’s European should you care.
With all that being said, I don’t really care much about what distro I’m using. What I do with it could be replicated with pretty much any distro. For me it’s mostly just a means to an end.
