My New Digital (i)Life

My iBook is coming, my iBook is coming! :) “Feb 7 or earlier”. I wanted a Mac Mini at first, but having two barebone computers felt a bit unnecessary. I’ve already practised some MacOSX in the PearPC emulator and ordered myself a small wireless router :). Only thing missing now is software. What’s the best (preferably free) FTP, IM and IRC clients out there?
