Saving precious in-progress essays went from file folders to floppy disks to USB drives — and now, it's all in the cloud. Thanks to services like Dropbox, all your videos, photos, and documents can go anywhere with you. Cloud storage saves files and syncs to all your computers, phones, and tablets. Should you find yourself gadget-free, you can still access work via the Dropbox website. So long to "forgetting" your homework at a home as a valid excuse in the classroom.
