I just got a second addition to our home. I currently have a 12" powerbook, and just got the 17" imac G5. Sweet machine. Now that I have these two computers, I am thinking about setting up a small network between them, and maybe this printer that is network ready. But first, why would I do this? This is the dummy part of the question. What are some reasons to have a network, pros and cons maybe.... Is it hard to set up? What do I need. I have two computers, and a wireless router. Thanks!
