Today, Google Docs released the ability to create Presentations (PowerPoint-esque slideshows).

Create a whole new slideshow in Presentations or upload an existing
PowerPoint file to get started. Kick your web-based presentation into
slideshow view mode and invite others to see it real time as you move
through slides—with chat built right into the sidebar. Make the
slideshow public or invite specific collaborators to edit and/or view.

Online presentation with real-time chat? Sounds pretty nifty. Look out, PowerPoint!
