When Leopard comes I'm going to do a clean install but I have a few questions, if I burn my applications to a disc, will I be able to install them on Leopard? Like, I have iLife '08 but if I re-install it when I get Leopard will the serial code not work or will I still be able to install it using the same serial code? Also I got iWork '08 and I did a online install so when I burn iWork to a disc will I still be able to use it when I install it on Leopard?
