Dropbox got big because iPhone users were so desperate to be able to share files between people and desktops that they started using it in droves. The desktop users that took it on were simply looking for some more storage and it just took off from there. There was no reason to pay attention to it initially (and still isn't imo) and over in android phone land everyone had no reason to either other than to retrieve files their friends sent them.

That’s not how I remember it at all. The first time I heard of Dropbox it was in 2010-ish (1 year before I got an iPhone and several years before iPhones had a usable file system) when folks in my dorm were using it to share music libraries. I was a CS major and had never even heard the word “samba” (yeah, I know) and it seemed super useful for all kinds of things.

I mean, that’s just me, but my understanding was that it didn’t take off on mobile until after it had established a secure foothold on the desktop.
