You have never heard a "real user" (and remember, you and I are "real users" as well; you don't stop being a real user just because you are technically inclined) complain about having run out of space and having to clear off space? About not being able to fit all of their music, photos, videos onto their MP3 player, phone, or tablet? I've certainly encountered that. And I can imagine people saying "hey, this has 32 GB of space, my current device only has 16, this will allow me to fit twice as much", without realizing that a full half of that space is not actually available.
