Had to Rearrange My Desk

 I've rearranged my desk so that I can use the Macs at one end of the (long) desk.  

This resulted in moving my 27" iMac, placing it next to my Mac Mini.  The enables me to use the iMac as a monitor for my Mini, using Target Display Mode (TDM).  I had to buy a USB-C to mini-Displayport cable and use the one of the Thunderbolt slots to connect to the iMac.

Even though I can use TDM, there's the issue of having two sets of keyboard and mice between both systems.  I don't think there's a worthwhile way around that issue.

I'm also using a bluetooth mouse and keyboard with the Mini.  The mouse is a Corsair Harpoon that has a bluetooth mode.  I'd been using that mouse with my work laptop until I found that it had BT functionality, then I repurposed it for use with my Mini.  The keyboard is a Seenda ISJ-ZXKB01.  It has mapped controls for MacOS.  It works well, but tends to take a few seconds to reconnect when it is hibernating (I've to tap a button and wait maybe a second or two for it to awaken before I can use it).

Since I took the iMac from my work setup, I am mow using my Dell 27" monitor as my second screen for work.  I'd previously been using it as a second monitor for use when I'm streaming gameplay, but since that system has a 34" UW display, I really didn't have an excuse to use an additional monitor.  It did make things a bit more simple, as I could use OBS on that screen while the main screen was outputting gameplay.  I may buy another 27" screen from Dell if I want to go back to that setup, but I'd have to rearrange the desk or get a wallmount for it (or the iMac).  We'll see.

The Macbook Air (MBA) is doing well.  I've been using it to do light things such as blog posts, research, and note-taking (using OneNote).  I'd heard folks with M1 Macs using the MS Edge browser because it's less resource-intensive than Firefox and Chrome.  I've been using Firefox as my main browser, but I've to watch it closely because it tends to consume lots of memory.  I might try Edge soon.
