murasame most ext hdd's for mac are firewire. If you have a g4 I wouldn't go usb, the usb cards in g4's were very, very slow (12 MBit/s.) HDD's where I am have certainly been coming down in price over the past couple yrs.

That's where the planes come to land in the harbour. They need to be waterproof though. You mean you've never been (swimming) at an airport. It is a wireless network.

I think I get what air port means in relation with a mac....
and now thanks I know I should get firewire cause dam 12 mb'spersec is slow.

I know my friend, I know. The only USB stuff I have are the keyboard, the mouse and a MIDI keyboard I use sometimes.
