My house came wired for cat5 (the original cat5!) but modern wifi is a lot faster than 100mbps, so I just use wifi for everything.
Latency is higher, but so is the speed.
Also I only own 1 desktop that has an ethernet port, and I haven't plugged the desktop in for 2 years.
I would actually like to have the TV hooked up to ethernet, since its wifi chip crashes every few days and I have to power cycle wifi in settings, but whoever wired the house for cat5 didn't install ports anywhere, although they did install a large patch panel in the basement, but I have better things to do than crimp a bunch of wires to fix one flaky connection.
