Back when I was in school, the only way to transfer data from home was on a floppy disk. Sure, you might have a CD burner at home, but the discs were rather expensive. Floppies were fine, because the only things you'd really save were documents and some Clipart for your book report. The real downside to floppies is they were terrible at actually retaining data. But what if you had a way to store files that would last 14 billion years?
