4.0 out of 5 stars Good intro to PowerPivot, July 28, 2010
Verified Purchase(What's this?)
The good:
* Excellent information on new features and capabilities of PowerPivot tables. Lots of good examples.
* Good compare & contrast with base PivotTables.
* Good documentation of some of the v1 PowerPivot limitations.
* The prose is very easy to read.

The gaps:
* The book was written before the final product was delivered. It would be good to see some errata/revisions covering changes made in the mean time for early buyers.
* Probably somewhat related to the above, the discussion of DAX is fairly limited. DAX is the real key feature that makes PowerPivot more powerful than base PivotTables. (The best reference source I've seen so far is the MS "Data Analysis Expressions in PowerPivot for Excel 2010" document.)
* It would have been nice to explain some considerations when moving models from PivotTables to PowerPivot. For example, PivotTables by definition have to have everything in one giant table. PowerPivot models end up working better with separated lookup (dimension) tables in my experience so far.
