I prefer desktops because is something breaks I have a chance of working around it immediately (e.g. screen), and if not then I can have a replacement part sent to me in about 24 hours or less which I can install myself.
It's better for the environment as well, because you're not throwing the whole thing out/leaving it to the whim of whoever is supposed to recycle it, plus you can selective change components that are bothering you - keyboard, mouse etc.
