ok i have just been given a mac G3? are they any good? i have never used a mac in my life so dont have a clue about them? whats the newest operating system because i think this ones a bit old?

is there any way to get files from my pc to the mac, can they share the same internet connection?

if anyone could give em a hand or point me in the right direction cos i know some people are very mac-knowledgable on here

thanks.
