I have a fixed standing desk with a tall bar-stool type chair I use for resting at times. I'm 50, but even with glasses I use just for editing (they are optimized for bringing into focus things at arms distance) I have the monitor relatively close to use it at the resolution and font-sizes I like. This means if I'm working on editing something toward the bottom or top of the monitor I'll often have to adjust its height so that I'm not tilting my head too far down or up. The monitor arm just makes that so easy.
After a couple tries, I found a knock-off of the Fully Jarvis arm that works well, the WALI GSM001XL:

Anyway, this LG is neat, but my 32" is already at the height limit I'd want for a monitor. I feel like this LG dual setup I'd need to have too far way to see the full view comfortably, which would mean running everything at larger font sizes, so I'm not sure it makes sense.
