As blogged, there's not much to write about; things these days generally just work. However...
Microphone
The internal microphone is not great. Quality-wise it does not compare favourably with the mid-90s beige Creative mic I got bundled with a sound card at the time, and use even today.
Wake On Lan
I use WoL for backup. The laptop does not have an Ethernet jack, but is supplied with a USB-C Ethernet adaptor.
I've also got two Lenovo docks: "ThinkPad Thunderbolt 3 Dock" and "ThinkPad Universal Thunderbolt 4 Dock".
Wake On Lan works via the version 3 dock, but not the version 4. It also only works if the laptop lid is open.
In the Laptop firmware settings (née BIOS), I have set "MAC address pass-through", so that the Laptops's internal NIC (apparently it has one, even though there's no jack?) is represented by the docks. I set this while debugging WoL, but I don't know whether it's necessary for it to work with the 3 dock (it wasn't enough to fix WoL with the 4).
