I bought one of these. In those days, I could keep the JDK in a box of floppies or it could fit in one Zip. Unfortunately, you had to carry your drive with you, because few people had one. So it only really made sense as backup media for me.

It was probably very localized, where my parent worked in the late 90s every office room had at least one, so my parents also bought one for home so they could easily transfer files.

It almost dissapeares overnight once 32MB+ usb drives became common, much more convenenient.
