I use wget for plain, old regular downloads a lot. If I need to save a file to a specific place (e.g. datasheets to a doc/ directory in my project) and I have a terminal already open there (which I usually do), doing wget and middle-click is far more convenient than dealing with the browsers' "Save to..." dialog. Especially ever since they started considering a sane download manager to be one of those confusing features that users totally don't want.
