Gotta say, I’m surprised with how similar our setup are, completely independently. A couple of differences, (which I will stick with!) I use the Logitech K800 backlit keyboard/m510 mouse combination. I like that you can pick and choose your combination, but the backlight on the keyboard is indispensable for me (different work hours?). One major opportunity you are missing IMO, is that I also have a Magic Trackpad under my left hand (mouse on right, trackpad on left). It’s indispensable for all of my swipe gestures, especially swiping between multiple desktops on each monitor. which I can easily do left-handed. Really surprised you don’t have this (but convinced you will once you try it!) I use the Belkin 3-in-one charger and it sits on the left in front of my headphones arm (Lamicoll) rather than the right. (I also have the Belkin 2-in-one <based on your review> but I ended up using it as a bedside charger as I like how it puts the extra watch “behind” my phone so I don’t see it at night. I originally got the 2-in-1 for a desk replacement, but opted to stick with the 3-in-1 there as all three stations are frequently used simultaneously.) My “real estate” monitor is a single 49” Samsung on a movable arm. Not quite the high res you have, but I like the single pane, and it’s good enough for my needs. I also use a secondary (tertiary?) monitor on the right, all driven by a 16” MBP, with display open (for any high res work) on a Lavolta stand. A lot of my time is spent in presentation mode and I use all three monitors simultaneously during that task. I round it out with a “retired” ipad pro on the left which I use for live whiteboarding.
PS I have 4 different (affordable) standing desks I have acquired over the years. “Fully” is what I have settled on as my re-buy/recommendation. EXTREMELY quiet and unbelievably stable throughout a wide range of height adjustments. (Including really low for a piano keyboard in sitting position.)
