2.5G is pretty common on new hardware, 10G is relatively common on high-end prosumer hardware. So not exactly zero progress. I think a lot of it is down to the realities that most people are only really interacting with the internet at home, and for the most part, speeds over 1gb outside data centers was pretty rare. So very little need to upgrade. No mass movement to upgrade, means fewer component sales, lower production means economies of scale don't apply. Meaning you're stuck in relatively early adopter territory for a while. I upgraded my home lan as well last year, my main switch is now 10gb copper, my desktop and nas are the only devices with 10g nics, a few others are 2.5, and my secondary switches are all 2.5g to save money.
