I can understand why some people want something physical/tangible while testing or playing in their hobby environment. I'm still a fan of virtualization - passmark scores for an RPi4 (entire SOC/quad core) are 21 times less than a per-single-core comparison in a 14-core 15-13600k (as a point of reference, my current system) and while am running 64GB RAM, can easily upgrade to 128GB or more on a single DDR4 node.

Hard to see to an advantage given obvious limitations, although it may make it more fun to work within latency and memory constrictions, I guess.
