G5 Bluetooth MUST BE BTO or NEVER
Just learned in September MacWorld (p.63) that Bluetooth, unlike Airport Extreme, cannot be added later. It is attached to the motherboard and therefore MUST be BTO if you are ever going to want it. So watch out all you early adopters. If you plan on having a Bluetooth phone or PDA in the next few years you better add the BTO Bluetooth option to your early order.
