On most consumer desktops and portables, they don't place floppy disks in anymore due to the wide popularity of USB flash drives, BluRay discs, and Secure Digital cards (I know, I'm a big nerd, you don't have to tell me!).
On most business desktops, you still might need a floppy drive internally for some reasons.
Keep in mind, you can still buy USB external floppy drives, so everyone can have a floppy drive.
Floppy drives today are hell for me, because they only store 1.44MB of storage. I need excessive amounts of storage on removable media (at least 128MB), because I save several computer related tutorials for online use on my flash drive (it's a 6GB flash drive), and I've taken up 4GB in the one year I've been using it.
Trust me. I've been using computers since I was 1 and a half, and I'm ethically involved in computers now, and I'm 11 and a half!
