Hands on with Google Presentations
 

Google unveiled the latest component of Google Docs, the long-awaited presentation component of its free, online office application suite. Like the word processing and spreadsheet components of Google Docs, Presentations are stored online and can be worked on collaboratively by a number of users at the same time.

As is the case with Documents and Spreadsheets, users can e-mail and upload documents to edit online. While Documents supports HTML, rich text, plain text, Word, OpenOffice.org, and StarOffice files, Presentations can only handle presentations created in PowerPoint, and those have to be under 10MB in size.
