I think it'd be nice if Dropbox can heat up the competition and offer some interesting promos. Google Drive for instance. Drive has its own benefits, a better ecosystem and also relatively cheaper price. That said I still think Dropbox does a better job on sync, large file handling and collaboration. Specially for people who are not tied to the ecosystem. A promo to get me moved to Dropbox can be enticing. Not just price but also a Dropbox built-in tool to handle the painful file-migration for me.
