Laptop displays are also a common frustration, though this has been improving lately. Still too many models stuck on 16:9 aspect ratio though, which is suboptimal for anything but watching movies due to lack of vertical real estate. By the time you've factored in all the taskbars, titlebars, toolbars, menubars, tab bars, and status bars you've got a keyhole left to peer through. This is less of a problem for those using something like i3 or Sway where half of those bars are hidden but tiling WMs just aren't my thing.
