Computers these days! They all want to stick you with a super-high-def screen resolution, which means there are more pixels on your screen, which means that photos look crisper and for you multitaskers you can fit way, way more things on one monitor.
BUT! It also means that (to my eyes at least) fonts, icons and my mouse cursor are itty bitty.
I’m not old, but a super high screen resolution makes me feel that way.
