Excel Services and PowerPivot for BI

I am really impressed with the enhancements in Excel services and the addition of PowerPivot to SharePoint 2010.  I'm going to have to write some sort of top 10 article on the two of them. Here is an example of a dashboard I wrote for the Shceduling Department and the Production supervisors published in Excel Services. The data is driven via T-SQL queries. The datasource can even be refreshed. I'm just amazed.

Stupid SharePoint 2010 Error:The Installation of this Package Failed

If you are trying to install SharePoint 2010 and you get the error message shown in the following image, you will need to redownload the installation file and try again.

I wasted an entire afternoon trying to figure out why I was getting the error above. I had installed all of the prereq's and my Server 2008 R2 was up-to-date. The executable would not even fully extract, so there was no error log or anything to help me troubleshoot. I hope this post saves someone some time.
