iLink is Sony Corp's implementation of the IEEE 1394 standard.
Apple's implementation of IEEE1394 is called "FireWire". So, if your camcorder has iLink it means it's FireWire compatible for your macintosh. If you have a mac recent enough to have FireWire, and got this strange wire in your original Mac box with a FireWire plug on one end and a tiny little plug on the other end, that's your FireWire -> iLink cable.
If you plan on editing your videos on your Mac, use firewire! It'll save you buying more (expensive) import hardware...(say, if you had a Hi-8 or BetaCam).
I'm guessing they've had them for so long because an i.Link port is realy cheap and easy for them to put on, whereas FireWire on teh computer requires a whoel extra bus?
No no no! I know that! I meant, the reason the really cheap camera have them is because it's nto as expensive for a port to be put on a camera as to put one on te computer! Don't worry, I know that it's the same thing (I use it afterall)
if you see the size of the pin hole for the port, it's more for efficiency and saving space. Look how small the port area is on a camera, usb, firewire, audio, video out, s-video all crammed together.
Adam, I think you completely missed the boat on that one.
Hypernate, to use Firewire/i.Link/IEEE 1394 in a device, no matter what the device is, requires a bus. You can't just stick a plug on a camera and hope that it will take the data from the media heads to the wire. You need a bus to transmit the data. Firewire is simply the easiest way to get data from a camera to a computer, which the companies want you to be able to do.
