I doubt anyone really needs it but, the nice part about the newer 9 and 10 speed cassettes is not really that you get any more range (it still starts at around 12t and ends at around 25t no matter what), but that you get more steps in between. It is nice to not have to ride a corn cob to get that feeling of finding just the right gear for the conditions. I have an old 12 speed, and the jumps with each shift are not at all subtle.
