I have been admiring and researching Macs since I bought my iPod last summer, and have been (and still am) saving up for the day that either a G5 iMac or G5 Powerbook arrive, as I'm dying (mainly) for iLife/Final Cut Express, and also the sheer beauty of the OS. However, I live in a household with two PCs (three including mine) that are wirelessly networked together (if you could call it that - my start menu and taskbar vanish then reappear every few seconds when I'm trying to get to shared folders on the others, and the windows randomnly close frequently). The main point of the network is that all three of the computers are able to share an always-on wireless internet connection (we have some D-Link thingamajobber in the basement that controls it). My question is (and this may be difficult without me sharing the finer details of the connection, but I don't really understand it) will my Mac be able to be on the network as well, and if so, what hardware will it require. I know our internet provider will hook up Macs, buy I doubt my family would be very happy if we had to pay two high high-speed bills a month, so I'm curious if my Mac-to-be can carry on the same function as my Windows PC is doing. This leads me to the only Mac product that confuses me - Airport. Would I need to have an "Airport Base Station" or whatever for the Mac to be on the network? Or just an "airport card"? Or would I need something else entirely? What exactly does Airport do? My final question, and totally non-network related, what is up with the green traffic button on the window bar? On Windows, I'm used to the button making an app go full-screen, but whenever I've tested it on Mac, it simply stretches the top and bottom of a window to the screen's constraints, leaving the rest of the window at its previous dimensions. I don't actually use full-screen a lot, but I wonder what the purpose of this button actually is, and if I'm missing something. Thanks for all your help, I can't wait for the next batch of G5 releases, and my transition.
