OneDrive - another choice for cloud storage

Update:  The extra 20GB is no longer active.

Many are you are probably familiar with Google Drive and Dropbox, but you may not be familiar with Microsoft OneDrive.   This service was formally called SkyDrive, but has been revamped.  I was given a link to share that will allow a friend to get an extra 20GB.  I'm not sure how many people can use it, but give it a try!

This might also be helpful for your students so they don't need to worry about bringing in a flash drive every time they are working on projects.

To give a sense of how it compares to Google Drive and Dropbox, take a look at the information below.

Free Storage: Dropbox - 2GB, OneDrive - 7GB, GoogleDrive - 15GB (includes your e-mails)
Apps:  All 3 have apps for iPhone and Droid, but OneDrive also includes apps for Windows Phone and XBox
Collaboration: All 3 allow you to share files with others, but GoogleDrive and OneDrive also allow you to edit the document right from your browser.

What is your cloud storage service of choice?  Or are you like me and have them all?
