It can be really fun, and one of the best things about Linux as a desktop experience is the brutally fast window managers the never crashed, never hang to load, and rarely if ever behave in weird and unexpected ways. But you have to be customizing it all the time, you have to memorize all kinds of special hotkeys, and it has to be really important to you to have things just right for a special workflow. Which might be the case if yours, say, a programmer or something like that. But it can be an awful lot of hassle to fine-tune things just the way you want them.
