Why should you shoot raw? If you're happy with the results shooting jpegs & money is too tight to buy another card then stick with jpeg... you don't HAVE to shoot raw.
The reasons why Raw is the better format have been explained already (I presume... I haven't read it all!) I shoot raw because it gives me more options and more control over how the final image looks especially for those times when I didnt get the exposure spot on but I'll admit most of my memory cardswere dirt cheap off ebay 
! Of course, you started the thread with a challenge to convince you...
