I have three systems . . . all have LS-120 drives. That makes it easy to share large downloads quickly. CDRs and CD/RWs are great . . . I have three of them as well . . . but it takes time to burn a CDR or RW.
I do all my downloads to LS-120 disks. That greatly lessens the chances of virus infected files getting into my HDDs. I also have them set up for emergency boot up.
The common floppy is really no longer needed. CDRs can be made bootable, so there is good logic to eventually getting rid of all 3.5" drives. Zips are a curious hybrid . . . not floppy compatible . . . and what's worse . . . they are made by (censored.) I never understood why they became so popular . . . good mass marketing, I guess.
Right now, LS-120 drives are borderline obsolete. They are difficult to find. About the only ones now available are made by Panasonic (Matsushita.) Looking ahead, for portable largh capacity media between many devices (laptops, desktops, cameras, etc., ) I really like the IBM Microdrive . . .now up to 1 GB in a Compact Flash form factor.
