the 3gb for allowing camera uploads was a sweet deal - I uploaded about 3 pictures to get it

and you used to get the 1st extra 500Gb for adding one file or for reading the user guide.
I also use the "cloud is a backup for something local" approach,. and every so often I copy C:/dropbox to somewhere else if I am feeling particularly paranoid
i think
box, not to be confused with
dropbox was another one that went bust. and sugarsync closed its free tier.
i had a free spare 10gb in pcloud, dunno if they are still in business...
