hello! i need to buy a webcam for my ibook to use in ichat asap to chat to my mate in texas. (im in uk). Now, i know you can use a usb webcam with ichat as that is what i used to use with it before, but i wanted to buy a firewire webcam. what are the main differences between the usb's and the firewire ones? im persuming the data tranfer is alot better with the firewire, thus better video and audio. do most webcams come with a firewire connection now, or do i have to look for a specific one? i was gunna get the isight but its too pricey for me at the moment so i was going to go for a cheap alternative! any suggestions? also, im in the uk - so if any of you know any firewire webcams avaliable here with a rough uk price then that would be so great! Im using OSX 10.3.4 on a g3 700mhz ibook. Peace, Creative.
