>> You have to maximize most windows to get it to show enough information.

At work I use 1 or 2 monitors plus the laptop screen (on Windows). At home I just use a single 55" 4K TV for my monitor and place apps center, left, right, and up top for rarely used stuff (on Linux). The desktop metaphor always wanted a big display but you're right - most Windows apps expect a full 1920x1080 for themselves.
