Documents can be shared in real time, without the hassles of attachments.
Share your work with your colleagues by inviting them to view or edit your documents. Several people can collaborate simultaneously, so there's no need to keep track of multiple versions and attachments.
Access your documents from any computer.
There's nothing to download; you can access your documents online from any computer.
Existing files can be uploaded.
Google Docs accepts most popular file formats, including DOC, XLS, ODT, ODS, RTF, CSV, PPT, etc. So go ahead and upload your existing files.
Give or view a presentation, even if your colleagues aren't in the same office.
Anyone who has joined in a presentation can automatically follow along with the presenter on their own computer. Presenting to multiple people is just as easy.
Safely store your work.
Documents are stored online, with periodic auto-saves, so you don't need to fear local hard drive failures or power outages anymore.
