Do you use Dropbox, and if you don't, what do you like to use instead?
Google Drive or Mega. Personally I don't use any of it that much. Used to store college assignments on Mega & Google Drive for some simple things that won't upload on Gmail (file size > 25 MB). I used Dropbox but hate to login to another site just to do that. Right now I use Dropbox for only one thing ,i.e, ButterCup :)
