No, that does not follow. If all dozen variants properly made Scheduled Tasks available than it would not matter that we do not have the one unifying linux desktop (and the gods be thanked we don't) and that we call them cron. In fact I state that all popular DEs solve those basic usability problems since a few years ago.
Ok. So there's something that compels them all to call it "Scheduled Tasks" and some unified way to find/navigate to it, shared language/terminology? Seems doubtful.
Compare the typical results for a Google search on how to add a scheduled task in windows to the same for linux. For the UI oriented answers on Linux, guess the chances it works on your desktop.
Great soundbite, but in the real world, things aren't always that easy. Like when you plug in a USB to Serial connector, and the driver doesn't attach.
For windows, a little google-fu reveals that you want the device manager. For linux, command line solutions are easy to find. Gui ones exist, but they vary, and aren't easy to find.
