RAW or JPEG, Canon or Nikon, PC or Mac if that's not enough, there's Dual Core or Core 2 Duo ... faint!
Shoot what works for you, don't go shoot RAW just because a magazine or a friend challenges you to. I write from personal experience as a professional photographer I shoot JPEG exclusively. From time to time, I have switched to RAW + Large JPEG thinking I might need the famed "extra exposure latitude" or "adjustable White Balance" benefit but as it always turned out, I post processed the JPEG and still get what I wanted. I always make a second copy of the JPEG files to work on ... and they still have a smaller footprint than I would with RAW.
Stop kidding yourself. Cheap storage isn't an incentive to shoot RAW. Cost of hard drives and large CF cards were not my deterrent, time is. I am a PC power user and have a Dell P4 3.0GHz Dual Core, 2GB 667MHz RAM, 3xSATA-II drives and 3xIDE drives in USB Enclosure and despite the "modern" hardware availability, I've found RAW workflow to be too time consuming, especially with the volume of images I work with. The best JPEG workflow app is ACDSee Pro when you have dual monitors (I work with 19" + 24" LCD) and I zip through 1000 JPEG images fairly easily. For editing, I use Paint Shop Pro 9 with a number of customised photoshop plugins and this too runs fast on my PC. I would require some significant investment in latest Core 2 Duo hardware or switch to Mac just so I can run RAW conversion at the same speed I process my JPEGs now.
Apparently I am not alone here. Other professional photographers share the same opinion and have completely dropped RAW because we just aren't getting enough hours in a day juggling work and family time. For what is worth, I have also evaluated a popular RAW converter called Bibble Pro which also handles JPEG. This is one unique tool that packs a lot of features in one interface. Unfortunately, I have trouble adjusting to it and reverted to my usual workflow in my comfortable studio environment
may i know how do you manage your digital asset since you have multiple files of the same image?
