Since the advent of the internet, the technology industry has been steadily moving away from local storage to remote, server-based storage and processing—what is known as the cloud. Look at music and movies: We used to play them from local media, but now they're streamed from servers. By keeping your own documents and media files in the cloud, you can reap the same advantages of anywhere-access and sharing. Productivity gains and reduced local storage requirements are additional benefits.
These services provide seamless access to all your important data—Word docs, PDFs, spreadsheets, photos, and any other digital assets—from wherever you are. You no longer need to be sitting at your work PC to see your work files. With cloud syncing you can get to them from your smartphone on the train, from your tablet on your couch, and from the laptop in your hotel room or kitchen. Using a service like those included here means no more having to email files to yourself or plug and unplug USB thumb drives.
