I use Dropbox like anyone else. I also use Google's version. But sneakernet is still a reality in my life. I always have four USB drives on me each containing different stuff. The way I work. I can transfer documents/drawings/photos to anyone anywhere (to their laptops/PC's), and receive the same from them also. The other parties need not be connected to any cloud/network. I think by far the majority of people still work this way.
