No. No one should shoot in RAW.
The fact that I've never shot in RAW shouldn't invalidate my useless above statement.
It seems that as we enter Digi photog and processing, there are certain avenues that you can take that develop into more time and money. You can pursue lenses, buying bigger and better glass, you can shoot in Raw, requiring more memory, and better computer (or a reasonably fast computer with more hard drive space and good organization software)plus the NEF software so that
PS can recognizeit, and that's not to mention going into things like tripod and head, brackets, lighting systems etc. So we all go down certain avenues and decide where we need to stop as we've satisfied our needs for the time (ie, many of us have SB800, but no more extensive lighting system).
Most that post on this site have gone down most of the avenues to a relatively committed extent. I've gone partway down the lens (one fixed, one kit, one tele) and I could go much further but decided to sit on these for the time being until my skills and eye improve a little.
The same goes for me in shooting RAW. I don't have the resources necessary to get the memory, software, the time, speed etc to continue to make Photography a passionate hobby of mine. Obviously every option in photography has it's merits, but it also has it's price.
