Ever since I switched to windows phone I've sorely missed having an official dropbox app. Recently I've toyed with the idea of moving all my crucial files to OneDrive instead. I have more storage on OneDrive and the WP OneDrive integration is very handy.
I'm thinking about having both cloud sync services point to the same local folder for the first few weeks. That way if I want to go back its an easy task (and I can keep using dropbox's superior public folder)
Has anyone else done this? Are there any potential issues (permissions, conflicts etc)
