My desk setup has a single 27-inch monitor with my work laptop on a stand next to it [1]. That's really all the desk space I can allocate to screens.

I don't want a laptop larger than about 13.5" because it wouldn't fit nicely in my backpack anymore. So, the only way for me to add screen real estate is to expand vertically.

That said, the bendy screen tech is far away from having a place in my life. I value durability very highly in my technology.
