Not OP but: I would love it to be built in. However, neither OneDrive nor iCloud currently work with the same ease of use and seamless function as Dropbox. And

Not OP but: I would love it to be built in. However, neither OneDrive nor iCloud currently work with the same ease of use and seamless function as Dropbox. And Dropbox (as with Google Drive) works across OS. So, my work computer is a Mac, and my Home Computer is a Windows PC. My Phone is an iPhone. I can access all of my files, anywhere, from any of these devices.
