Um, yeah.  I just put a pivot table in an Excel file I use to track my Target expenses by category... (in a workbook that also details my CVS deals, health expenses, and other fiscal data). 

Does that solidify my PC-fueled dorkness to a new degree, or simply illustrate a subtle merging of my corporate report-centric workdays with my personal financial management? 

Either way .... I still get a warm, fuzzy feeling when the computer calculates things for me...and makes the data look pretty....and ESPECIALLY so when it does it automatically!  Go pivot tables!  (and to think I was almost reduced to tears of frustration when first working with them back in my Quality & Productivity MBF days in '04..... )
