I'm going to be buying a Powerbook G4 12" - my first mac in over 10 years! I currently have DSL with a PC desktop hooked in via Ethernet and a PC Laptop with a Dllink 802.1b wireless card. Question - do i need an Airport base station in addition to the card for the Powermac? I already have a wireless gateway which was given to me by the DSL company called a 2Wire. Will i be able to use the G4 wirelessly with the 2Wire and without the Apple Base station?
