This is free cloud computing. You can log into your workspace from any computer connected to the internet. The main drawback is you can't work off line. Between the email, documents and photos you have over 9 GB of storage. If you would like another 20 GB to share between the three aps, it's five dollars a year!
"Only stored files (.PDF, .DOC, .JPG, etc.) count towards your storage limit. Google Docs formats don't use up your storage space."
At these prices for secure storage keeping your data in house is expensive by comparison.

Google Docs offers the common file formats.
With a limited number of fonts available.
