No you're right it's not resource hungry: if you have an empty (or sane) ~/.emacs and ~/.emacs.d then it is completly fine. However if you have the habit of opening a new instance from the command line for a given file rather that go back to your already openned emacs instance, like I do, it will add up rather quickly (and the buffers won't be shared accross these multiple instances). With spacemacs it becomes particularly problematic (especially in regards to start up times), and I think that's where the emacs daemon truly shines. (edit: also no complaints here; I just feel this daemon is great and wanted to share the sentiment; it also felt relevant as AFAIK vim has no such feature)
