Just curious as to which macs are you go to devices. For me I rotate my computing needs between my 2011 macbook pro, 2006 El Capitan Mac Pro and my 2.3DC G5 (using it now). If I need to do some serious work I generally use my macbook as I've maxed out its specs and it flies. The mac pro is usually for watching videos and other media consumption as its connected to a 20 inch cinema display. Finally, when I simply want to surf distraction free the 2.3DC G5 surfs the web great thanks to Tenfourfox.
