My current bedroom desktop setup...
When I use my M1 MacBook Air in Clamshell mode, in addition to still hooking the Air up to a CalDigit TS3-Plus Thunderbolt 3 dock daisy-chained to an Apple Thunderbolt Display, I also now have an Apple Magic Keyboard with Numeric Keypad in Space Gray! I always thought the black keys with white lettering looked pretty cool. Maybe someday I'll get a Space Gray/Black Magic Mouse, too. I also now have a Magic Trackpad, for if I want to zoom and swipe documents and such while in Clamshell mode, after being so used to Apple's multi-touch trackpads for over five years now. I also use that G-Technology 4 TB Thunderbolt 3 external HDD as a video edit drive.
