Just things like waiting on the download for an Xcode update before I can get to work would be a lot more tolerable on 1.4 Gbps than the like 600 Mbps on the WiFi 5. Or worrying if this video is buffering because a backup started in the background.

But I gave up on waiting and just got Ethernet put in in the places where I'm likely to sit with my laptop - now I plug in to charge and automatically get 2.5 Gbps Ethernet at the same time using a USB-C dock and a long USB 3 cable.

With NVMe NASes and 5Gbit, 8Gbit and 8Gbit FTTH available for reasonable price in many places, it's easy to saturate any WiFi connection by just downloading stuff (games, AI models, etc), backing up files, or accessing your files on NAS (and editing videos straight off NAS is recently trendy).
