If this cost $5 more and had the M.2 slot and some way to access it reasonably easily, I would buy one immediately. Without that, I probably won’t buy one at all.

This thing is a desktop computer. The degree to which the performance is improved by using good storage is huge. Excellent NVMe disks in the M.2 form factor are cheap and widely available. Excellent SD cards are not so easy to find. Excellent USB devices are not as good as their M.2 counterparts, are more expensive, and are sufficiently awkward dangling out the back of an RPi 400/500 that’s it’s barely worth considering.
