Plus anyone with a not-cheap-ass Windows / Linux laptop, and anyone who's bought a desktop monitor in the last several years. I can't remember the last time I had to use a screen that wasn't.
What's "not-cheap-ass"? The standard "developer spec" type laptops from Dell etc. seem to still come with 1080p screens despite costing upwards of 1k credits. If you search for 27" monitor on Amazon you'll find 1080p models coming up, maybe some QHD ones. I can't imagine many offices kitting out with 4K monitors unless they actually need them.
