Rounding out its online browser-based office productivity suite, Google today launched its presentation building tool, a competitor now to Microsoft PowerPoint.  The tool will let you build out a complete presentation slide set which is accessible to any PC with an Internet connection.  On top of that, the application will import and export to the PowerPoint file format.

Probably the greatest strength of this new presentation tool is the collaboration features already in Google Docs.  Now you can work with multiple people cross the globe (if needed) to build and perfect a presentation.  This could be huge for anyone working on projects with team members scattered between different geographic locations.

Google Docs is a free service, all you need is a Google account.
