Nerds used to large corporate networks/university ones pretty much all had access to shared drives that "just worked" in the OS file browser.

The magic of DropBox was that non-technical users could just share that word document, have it everywhere and not have to deal with a weird terminal.

I wished Drobox built a (physicals, why not) wall at their HQ with the names of everyone who was able to miraculously recover their masters/phd thesis after hardware failure because they saved it in their Dropbox folder.
