Hi Lisbeth and welcome to the 123PPT Community and PowerPoint Forum.

Office PowerPoint 2010 is the latest revision to PowerPoint, following PowerPoint 2007 which was the largest revision to PowerPoint in the Microsoft history.

Perhaps most startling Lisbeth for you coming from PowerPoint 2003, is the new interface in PowerPoint 2010.

Microsoft claim that the new interface is designed to aid user interaction with PowerPoint 2010, and more easily find and use program capabilities. Naturally as with any application that we become accustomed to,  updates, changes, and radical redesgins, do take sometime to get acquainted to. But persevere because the all new look PowerPoint 2010 as with PowerPoint 2007, is certainly worth it.

You can use the Animations tab on the Microsoft Office Fluent user interface in Office PowerPoint 2010 to add animations to a presentation or even custom animations to a specific part of a slide. The features are presented in a streamlined manner, making it easy to find exactly what you need, when you need it. And you can use the Slide Show tab on the Office Fluent user interface to set up your presentation or even create custom presentations. This tab gives you easy access to all of your PowerPoint presentation options, making it easy to get started and customize the content you want to present.

All in all Lisbeth PowerPoint 2010 really is superior to its predecessors such as PowerPoint 2003, PowerPoint XP, or PowerPoint 2000.
