Google Presentations
Presentation is now one of the choices available in your Google account.
View this image gallery of how I created my first presentation with Google Presentations.
Just like Office? Not exactly, but the familiar "Click to enter text" text boxes are ready and waiting.
Not too many themes available, but they are clear, load quickly, and look sharp on the Web.
I'm a tree-hugger at heart. I had to go green here with the "Grass Theme".
Title slides, blanks, standard text/title, two columns, but no charts yet.
Slides can be manipulated in the left frame and edited in the right.
The file menu has quite a few options, including importing PowerPoint files.
Text boxes can be dragged around onscreen, resized, and otherwise manipulated in standard PowerPoint fashion. Right-clicking also provides a context-sensitive menu, but no copy and paste for the elements yet.
Slide shows can be published to the web so that you can conduct an online slide show or just allow others to view asynchronously.
Here's how it looks shared; others can join in and view simultaneously.
While this is very similar to the shared slide view, it is controlled from within Google Docs instead of from the URL to which you publish. It also has a nearly full-screen appearance.
