I used to use my personal mbp for work, since I found windows extremely annoying for operations work (it's only getting slightly better with alacritty and windows terminal...) and my client wouldn't provide me a mac. Almost two years ago I tried installing Arch linux on the laptop they provided which was gathering dust, and I was surprised that almost everything worked perfectly out of the box (except for the fingerprint reader).

They're using Office 365 too, so I tried using it in the browser (Firefox) and I loved it so much that I can't use the local outlook client anymore. It just feels sluggish, and I hate that I have to let go of the slider when scrolling to see the message list update. I don't think shared mailboxes are handled very well, though.
