I never really gave this much thought, but really, why is C the main drive in Windows, while A and B are reserved for floppy drives? Wouldn't it make more sense if the main drive was A, and they had treated floppies like cdrom drives where they just take the next available letter?

Random thought of the day.

Just a remnant from the early days of DOS. Not sure why it's still like that.

Drive letters are an annoying relic. Wish MS would ditch them in Win8.

Way way back when older pc's had two floppy drives, "A" and "B" were reserved for them, this became an industry standard and hasn't changed in over a decade. Have tried using "A" or "B" for a usb drive with poor results.

I've got a question: Why is my MagicJack phone recognized as a CD-ROM?

Likely because it fakes the interface so that it automounts and can autorun a driver install when you plug it in to a new machine. I don't have a MagicJack, but that's my guess.

For the same reason that the universal Save symbol is a floppy disk: it just is.

More precisely, that's what the old people who run things grew up on and are used to. Wait until the baby boomers have mostly died off and X/Y/whatever will probably change it.
