Google Announces Google Presentations

"We've already freed those of you working in teams from the burdens of version control and email attachment overload when going back and forth on word processing and spreadsheets. It just made sense to add presentations to the mix; after all, when you create slides, you're almost always going to share them. Now students, writers, teachers, organizers, and, well, just about everyone who uses a computer can look forward to having real-time, web-based collaboration across even more common business document formats."
