It has all of our asset management systems in one place! I can easily see what equipment we own, where it's located at different sites, who owns each piece so that when there are issues or problems with something, someone knows exactly which department to go talk to about getting them fixed/repaired/maintained etc.
The only thing I dislike really is how slow some things load compared to other programs like Excel (which isn't much slower). We use this software as part of an overall system called EPM360 - but have found elements xs3 more useful than anything else within the 360 program suite.
