Now I'm a (traditional?) dropbox user, using dropbox as a synchronized folder between various computers combined with a remote backup. All I would need to do to transfer is send a few links to people to my new shared stuff (folder / album )
My only technical issue with transfer is actually transferring the file from Dropbox to Google ( 1 MBps upload ) and getting all the machine synchronized.
What keeps me on Dropbox is a few years of flawless reliability. I still remember the dark times of syncing before dropbox, YMMV, but I intent for losing files, silent conflict, ... to stay a thing of the past.
However, first it was https://hubic.com/en/offers/, now Google. Even box.com is significantly cheaper. In a few months, that will be difficult to ignore, I hope dropbox is listening.
