Box is offering a limited time offer of 50GB of cloud storage for new sign-ups. Registration is completely free and takes only a minute or so. You can then download the free Box app for iPhone and iPad, allowing you to access your content from anywhere. Share files, view documents, photos and so much more. This could also serve as a backup for important files on your computer. When you consider that Dropbox offers you 2GB of free space, you’ll be picking up an additional 48GB from Box.
