Much awaited browser based presentation tool, has finally arrived, Official Google Blog:
Starting today, presentations — whether imported from existing files or created using the new slide editor — are listed alongside documents and spreadsheets in the Google Docs document list. They can be edited, shared, and published using the familiar Google Docs interface, with several collaborators working on a slide deck simultaneously, in real time. When it’s time to present, participants can simply click a link to follow along as the presenter takes the audience through the slideshow.
Wait, it gets better: The audience can use Google Talk to chat during the presentation.
