And it's almost impossible to find ones that get as bright as Apple monitors for less than Apple charges!
My absolute favorite feature of Apple displays is that I don't need to have the brightness cranked to max all the time, even when sitting next to a window. Some of them are, dare I say it, too bright for a normal office at maximum brightness (yet still dim for comfort in a pitch black room).
There are some good alternatives if your budget stretches to $1000, though: Samsung's 27" ViewFinity S9 comes to mind, with 2880p and 600 nits.
