I need to setup a network for a friend that is buying a Mac Pro and a Mac Book Pro. The MBP will be wireless and the MB will be wired. I have messed with Airport Exteremes a bit but was wondering is their any advantages of using an airport extreme over a linksys router or something like that. I do like the fact that the Airport has a USB port to share a printer. That is a perk but not a must. So some of you experienced mac users give me the heads up on why I should use the Airport over another solution.
