Software Senescence: Google Imitating Microsoft?

When I first installed Google desktop search, I thought it was awesome.  It did an amazing job indexing everything from my Outlook email to the files on my hard drive to my Internet history files. 

A couple of months later, though, I am not so thrilled.  In particular, Google desktop search seems to be missing all kinds of hits in my email.  I will get no email returns from Google but then use the "find" function in Outlook and get 20 hits for the same search term.

This is very disappointing, because I was so fired up about the product initially.  It seems like Google software may be subject to the same senescence issues that seem to be a fact of life in Windows.  Since it is both free and a beta, I am perfectly willing to cut them slack, but I do hope they get the kinks worked out.
