The title explains it. Now the reason that I'm making this thread is because even though Macs are awesome, they become even better with mods. What kind of mods can you guys suggest? I'm interested in: A Windows Media Center alternative for Leopard (Quicktime Sucks! =P) A good video decoder An anti virus A free Parallels/ VMWare alternative And other misc stuff that you guys can't live without! Dashboard widgets can be added too.
