*iCloud lets you store only specific types of files like photos for free. To store iWork documents in the cloud, you need to purchase iWork apps separately.
**SkyDrive works with the Microsoft OneNote mobile app for Android to capture anything on the go.
***Google Drive is focused on document storage. Google offers separate products—Google+ and Picasa—for photo storage and sharing.
