Hi, I mean, that if you run the Mathematica kernel alone in a command line session or Unix shell, than you need %. Historical it was so that Mathematica 1.x where a program that run in a text mode interface with an "In[]:=" prompt without any GUI interface or copy/paste. On Mac's this was different because a MacOS < 10 had no command line, but on the most Unix systems or if you don't run a XWindow on the machine this simple interface still exist and if you use Mathematica in this way % is very usefull. Today, where the most people run Mathematica from the FrontEnd % is alsmost useless, because you can evaluate the cells in an arbitary sequence and you can't never be sure what % mean in a Mathematica notebook.
