Maybe you can't, and that's fine. For me, being able to work on stuff on one machine, then jump over to another one of my machines and it's just there is hugely valuable. The backup element is kinda secondary but nice to have.

This is exactly why I use Dropbox. Backing up, sharing files with others may one day be handy sure.

Having files on all of my devices without the effort is why I pay them whatever their monthly fee is.
