Computers have made it common to work with coworkers in offices all over the world. That means file sharing has become a key part of professional productivity. When you don’t share a desk, you can still share the contents of your computer’s desktop.
Dropbox is probably the first name that comes to mind, but another you should consider is Droplr. It turns file sharing, screen captures, desktop videos, and other super useful collaborative tools into a simple drag-and-drop affair. And right now, you can get 4 years of Droplr for up to 3 users, for just $39.99 at Cult of Mac Deals.
