Google Presentation
Google updated recently their Applications suite with the addition of Google Presentation. It was added to all of docs.google.com including Google Apps For Your Domain, which I also use. 
Nice things in this application
- It looks just like PowerPoint!
- Great Revisions support - many copies are saved all the time, so you'll never lose anything.
- You can start a presentation then give folks a URL and they can join up and watch.
- Upload a PPT .
- You can chat about the presentation being watched.
- Save as a ZIP file. They'll create a "self-contained" ZIP with a single HTML file and the assets you need to run the presentation using any browser.
But there also annoying things:
No spellcheck support. Can't link to pictures online, have to upload. No animations, shapes, auto-layouts, wizards, etc. Very basic. No PowerPoint-like experience on the web. JavaScript errors. You can upload PPT, but you can't Save As PPT.
Nice application but I think I'll wait to the next versions.
