I have a white 15" ibook and I believe the firewire port is broken. Is this a common failure and what are your comments concerning my options. 1. Mother board change (costly) how much? 2. Use USB and put up with the slow speed? 3. Are there any other options? -- Larry Blodgett email: (lblodgett at mac.com) email: (lblodgett at macosx.com) In theory, practice and theory are the same, but in practice they are different.
