Copper vs Steel pipes

I'm just wondering what are the differences/issues between using copper and steel supply pipes for water. I need to remodel a shower and am wondering why I would use either. I have an older house with both. Is the main difference that copper wont rust inside?
Thanks for the Info!

Main reason(s) are that it won't rust and will not flake off in a few years, clogging your fixtures. If you remodel with copper and have to tie into a galvanized steel line, you must install a di-electric union. If you don't you will have a condition called electrolosis that will eat away at the pipes in the area they are joined at. This is caused by joining dissimilar metals. It is a chemical reaction.
If you use steel pipe, you will have to put up with rusty water whenever you turn on the shower. Good luck.
