I'm planning on getting a linksys router. Both my roommates have windows and I was wondering if there will be any problems commecting the 3 computers with cable if I have a mac. We went to best buy, assuming that the tech guy held the answers. He said that macs are not compatible with PCs and if we want to connect all 3 computers, we would have to network the PCs to recognize the mac. And since we're dumb girls, we won't be able to figure it out. So he suggested that we bring in the 2 PCs to best buy and pay to have them install for us. Now, The apple-guy at the apple store at my school said that was bull and you can just plug it in.. and viola. True/False?
