Then, there are the details that we take for granted but people in the Windows world cannot. The Mac knows when you insert a floppy disk. With iMac, Apple is effectively saying that floppies are on their way out. Soon, the few pieces of Mac software that still ship on floppies will switch over to CD-ROMs. For software distribution, this is great.
Floppies are notoriously unreliable and slow.
Though the road to a floppy-less world is likely to have a few ruts, I, for one, am glad we're finally moving in that direction. Actually, it's more useful now than ever. You can be sure that it'll come in handy for installing software shipped on floppies onto the iMac. Since the late '80s, Apple has provided a free utility called DiskCopy for Macintosh users. After acquiring a disk image from a CD-ROM, online service, or wherever, you could use DiskCopy to make a floppy identical to the original.
