To be honest I haven't installed neither used it. But from the real reviews, user feedback and when looking at the screenshots themselves, I gotta say... it looks promising. There are a lot of differences in the Pinguy in comparison with the Ubuntu which it is based on. For instance....
*. When you double click on a .iso file extension, unlike opening it with archive manager (which is the default behavior for many Linux distros), Pinguy will open it with the Braso CD/DVD burner which makes sense, and this can be seen with other file types as well.
*. Shotwell photo manager is installed by default, which is a great application for managing pictures (from customizing them to uploading to online photo sharing severs, etc).
*. If you want a MacOS Dock like app then you'll love the Docky application that is preinstalled.
*. Out of the box, it supports a lot of different types of multimedia files which are "dropped" by major Linux distros. Java and flash player support is also included and many more.
