JPickett -- Treeseeker & bws48 covered it. Since we do have multiple PC's, we use a D-Link splitter on the Ethernet connection to get multiple Ethernet connections into a single connection to the router. Works good.

Another advantage is that Ethernet has a higher download speed than the wireless connections I've seen.

The iPad and iPhone do use the wireless connection, but I don't do sensitive stuff on them.
