Hi, as I'm waiting for my new iBook I'm preparing my desk for it too. As I need to drill a couple of holes to thread through cables, can anyone please measure the width of the power output plug, not the end that goes into the wall but the end that goes into the iBook with the amber/green ring light. Just the width for the little cylendrical plug will be great, that way I know it will fit though the holes I drill. Thanks,
