I think the new stuff feels a bit like stagnation to a lot of people. Personally I noted that 4k monitors and 10g networking were the future years ago and just haven't happened in a real way. The monitors never came down in price. 10g SOHO scale gear doesn't seem to exist except single uplink sfp ports on 1g stuff. I replaced a 10 year old home server and the new gear isn't much faster, the difference is size and idle power consumption.

I would agree SOHO gear has stagnated big time, and yeah power draw is definitely not something to be overlooked. Latency is also kind of a thing. Newer gear can often be snappier while it uses less power. Now middle-grade enterprise gear is basically the same way. You can't really get a 24 port 10g switch for under $3000. The prices tell you everything. You buy the cheaper used gear and you pay the price in learning curve or tech dept.
Funny I did a little consumer hardware comparison. There is a reason the Ryzen 5900x is still holding it's price while everything else fell off. Because the price/performance (platform + memory included) isn't worth it. I've been looking for a cheap 5900x to upgrade my workstation to.
