The article says "The first 3.5” disks could only hold 720K". Actually, the first 3.5" disks were 400K (Mac formatted). They then quickly went DD (double density) - 720K on PC, 800K on Mac, 880K on Amiga - same disk, but different capacity depending on filesystem. It doubled again with HD - 1.44Mb on PC, 1.6Mb on Mac, 1.76Mb on Amiga.
