Don't forget CVS

I still use it for NetSBD source

I use FTP mirrors for various source code

I use FTP for moving files to and from mobile phones

I have never used Dropbox. That company made some people wealthy no doubt but that doesn't help me

I also use USB sticks extensively, e.g., primarily for booting computers, but also for data storage

I have broken a couple when using them in non-NetBSD OS but never lost one

it was a moment in time, but at a past company I implemented svn on top of Dropbox for the team to share code remotely. and it worked just fine

I am just like you except for the netbsd source part, and I have my own private cloud/nas with virtualization. I also at one point just started using AWS S3 as my personal dropbox on chrome for sharing files with myself, since I backup encrypted snapshots there from my cloud anyway.

but I think there are many people out there that love a gui for storing files in the cloud. i know my parents/parents friends' all use it.
