I shoot RAW+JPEG Fine. I like the JPEGS for my collection, it has given me the ability to see the picture in my windows files and I can rename them quickly and add to my excel spreadsheet (I am very organized and a bit OCD when it comes to how things look). Anyways I use my RAW photos for uploading to airliners/jetphotos, that way I can extract color, exposure, etc that I wouldnt get from JPEGs. My 2 cents.
Manny, my only concern is if I could have the same excel spreadsheet database that I currently update with lightroom, I did receive a 30 day trial with my purchase of Photoshop Elements 10. Maybe you could pm me and enlighten me about Lightroom.
