I use Dropbox every day in my business! I have it synced to my laptop and phone, so my files are constantly backed up. In addition, I use it as a vital tool for social media posting, as the 'export' feature makes it easy to post directly onto social media sites from my phone. In addition, I can share files and folders with clients and colleagues. Dropbox saves me time AND makes me more efficient. What more can I ask for?!
