No, that is not a screen shot of Keynote, it is from an online slide creation tool called 280Slides. The interface though is so similar to Keynote that one might accuse them of just ripping off Keynote, stripping it down and turning it into a web application. Indeed in reading thru the few blog posts it seems that the developers have a Mac bend. Given my preference for Keynote over PowerPoint (“Power Corrupts. PowerPoint Corrupts Absolutely“) one might guess that I like the interface of 280Slides. Like Keynote it is designed more towards a visual presentation and less towards putting text on slides.
280Slides is relatively easy to use, and comes with the advantage of other web applications, i.e. working from any computer, accessing your presentation from any browser, not worrying about file compatibility, etc. And, while I might prefer 280Slides to something like Google Presentation, this still finishes a distant second to SlideRocket (which I reviewed here).
