I get battery life similar to Windows on my X1. I regularly share my screen on work-related meeting and it works for me without any issues on Gnome with Wayland.
I no longer use a Linux laptop for work but as recently as a year ago, plugging an external monitor/keyboard in to my X14 wouldn’t wake it up (required manually opening and closing the lid), I could use the headphones on AirPods but not the mic, and screen sharing on teams (and a bunch of other video conferencing software) would only work on X11 and not Wayland.
This was running the latest Ubuntu at the time (20, and then 21).

This is still the case. I was just trying to get this to work. You can't use the mic on a Bluetooth headset. There's supposedly a workaround that requires you to install and run a smartphone software stack on your laptop, but I could never get it to work.

Is this supposed to work on Mac? Does it need configuring? Is it something I need to enable? I always had to remove and reinsert the power cord to wake a sleeping docked Macbook.
