Which of the 180 or so raw formats are you using for archival storage?
Every digital camera in the world shoots in RAW. To record a digital image from a CCD or CMOS is otherwise impossible.
The choice from there is how to develop it in a manner that can be displayed on the web, printed, emailed, or opened in more then a hand full of computer programs that are all incompatible with many RAW formats.
I choose to let a processor specifically designed and optimized for developing RAW images do the work. The manufactures of my cameras developed that processors to work with their CCD or CMOS RAW format and gave me many controls on how it is to be rendered, many of which have dedicated buttons for quick access. This is what the JPEGs out of a camera are, RAW data developed into a JPEG on purpose built hardware with optimized software.
If your obsessive, then perhaps a program like CS5 and significant labor can improve on the product, but we are talking about Aperture here.
Aperture at best has weak RAW controls for the cameras it does support which sure isn't all of them.
I have far more specific control in my camera then using spray and pray RAW recording in the hopes of making a usable picture later.
Better yet, the camera has an awesome screen on the back of it where I can look at the picture I just took, see if it is to my taste, and adjust and reshoot if not, no trip to my computer to develop the RAW and back to reshoot required π
As I said before, opinions abound and mine is likely minority. Try both. Just don't feel inferior if you decide JPEG looks just fine.
Interestingly nearly everyone I know that earns their living with a camera shoots JPEG, but I come from a journalism background and time is money there.
Context matters. If I knew this very day I would be paid $100,000 for a picture that was going to be blown up to 40"X80", I would shoot film, and medium format at that!
I don't lug a medium format camera with me everywhere because they are big and inconvenient!
Never the less, medium format is VASTLY superior to any prosumer RAW camera available.
I don't shoot RAW on the cameras I do have because, if the camera is good and controls are set right, the difference is minuscule for a lot of inconvenience and labor.
But I'm posting on a computer forum so the correct answer here is: get a bigger computer, bigger hard drive, more memory, and use the most computer intensive method to record images or your work product will suck LOL π
Heres a gallery, all shot in JPEG

Have a look for yourself. Since it is personal fulfillment you desire, it is entirely subjective anyway.
Have fun. The pictures you take are always better then the ones you don't.
