Good thinking che! Why they don't stick the sockets on the front of these machines puzzles me. Well, I do have a neat little socket on me speakers saying "line-in" - but of course it doesn't work, so I've had to fiddle round the back and disconnect everything else by accident while I'm doing it.
Mind you any time I grumble about it, I pull myself up and remind myself that it's all an incredible miracle, and I've no idea how it works - and most of the time, it does work. Alleluiah. (And we waste our time and energy using it for silly little quarrels and so forth...Humans are funny creatures.)
