Yes I'm fully aware you can use Camera RAW to edit JPEGs. Its not just CS3/4 either, you can use Elements 6/7 or Lightroom as well. I even use it for editing JPEGs from my P&S (as it doesn't have RAW) as its such a good tool. However it is no quicker to use the JPEG than the RAW so you would have to be crazy to use a JPEG if you could have had a RAW.

That is simply not factually correct. JPEGs are 8 bit RAWs are either 12 bit or 14 bit. This means there is more information in the RAW than the JPEG and therefore possible that something is lost in JPEG but not RAW. You will get more noise when adjusting exposure/brightness in JPEG than RAW because your editing program will need to guess more as it has less data to work with, this is especially true when increasing brightness of shadows.
