Now I know I can install jaguar on an external HD and start it from there, but I was wondering what sort of performance loss could I expect, or is there any? Actually I'm planning on installing it on my iPod...is that a good idea?
Why didn't it work? You say that you installed it on your external HD, but that's shouldn't be any different than your iPod. What did it say when you tried to install it on your iPod?
