My point was not to debate MiniDiscs but that just about everything the OP is using to support their argument is factually inaccurate. It's basically gibberish with a little ZOMG APPLE/IPHONE indignation morsel thrown in at the end.
The OP was correct about saying that you need line-in. That’s what I, too, always perceived as the major downside of MiniDisk. (He said micro-in but already corrected himself on that. An honest mistake, he actually meant line-in. That doesn’t make it gibberish.)
