       | power hungry and, unless you're careful about switch selection,
       | can be noisy. It just wasn't worth it for me.

         | It's not what I saw a bit more than a year ago when I changed
         | my PC. A PCI express card was about 100EUR, about the same for
         | a switch IIRC. It was about 500EUR total for what I wanted to
         | do, not worth it for me.
         | 
         | The same hardware just Ethernet would have cost 5 or 6 times
         | less!

       | power consumption and price-tag. Even now, 15 years later. I
       | guess standard's authors had a little bit too much faith in the
       | Moore's law.

         | Yup, decade later and the market for 10G consumer switches is

         | 
         | Were I to guess, I'd say it's probably due to internet speeds
         | in the US taking forever to get up to 1Gbps. There's little
         | reason to push out consumer switches faster than 1Gbps when the
         | inbound internet connection only goes up 100Mbps.

           | To add a 3rd more minor reason: for the prosumers DACs/fiber
           | is faster, cheaper, and uses less power. The only reason to
           | go to 10GBASE-T is for cases with existing cabling where
           | 2.5G/5G might make a lot more sense if you don't absolutely
           | need 10G. For everything else go 10G/25G passive DAC or
           | fiber.

           | I agree with your guess. But we're starting to see more than

           | 
           | Xfinity sells 1.2gbps (used to be 1gbps) and 3gbps (used to
           | be 2gbps) to homes, but the upload speeds are horrible. At&t
           | with its fiber offerings just announced 5gbps speeds, but
           | they're very expensive and have horrible practices that
           | prevent you from using anything but their router.

       | consumer network kit, we could do with some openWRT/DDWRT/Tomato
       | Wifi 6E capable routers able to do CAKE QoS on gbit fibre. Rather
       | than having to hack a raspberry pi 4 together with a consumer

       | 
       | What I want is 10GBASE-T and wifi 6E and the performance to route
       | 1gbit/s with QoS and I would like it for something more like $200
       | or less. $250 for a couple of 2.5gbit/s ports on a switch is just
       | not worth it.
