With this new control it is the little things that make the new control worthwhile.  For instance when paging through the report, there are nice animated transitions.  This makes the paging experience elegant for users. 

When the user of the report drills down, a tab opens within the viewer.  This way the report is open at the same time as the drill down.  It is extremely simple to get back to the original report this way.  See Figure 2 for an example of this.

For the end user exporting, the addition of XLSX allows exporting to a Microsoft Excel Workbook.  Limited testing proved that this export put the data in correct columns.  That looks like a clean export experience.

For the report designer the experience includes the ability to preview the report while designing in Visual Studio.  You can upgrade to Crystal 2008 if you want the ability to edit on the preview page.
