JPEGs are fine, Brian.  Don’t listen to the mockers – if all you want to do is 
produce images which you will only slightly tweak.  

However, just look at the histogram of a JPEG before you do some serious 
adjusting (Auto Levels is a good example) and then check it after just one 
process.  You will see quite a bit of the graph missing.  Likewise, try saving 
and opening a JPEG a few times and a similar process will become apparent, 
although less quickly.

I use JPEGs all the time, but with a RAW file for tweaking in case I want to.  
Most of the time my Fujis produce pretty fine images with little fiddling.  The 
difference is an extra 15-20Mb per shot, and I weed my collection quite 
frequently to slow the buildup of storage space used.
