I have a PowerBook G4 Titanium 1Ghz and i want to upgrade the wireless on it from B to G. Is there an internal way to do that (replace the original airport card) or do i have to use a wireless card in my pcmcia slot? I wouldent mind using a wireless card in my pc slot but ive heard that i would have to remove my original card in order to use it. Is there a way that i can just plug the wireless G card in when i need it and take it out and use the internal card when i dont need the extra range? I dont want a bunch of things sticking out of my mac and ruining its good looks.
