I noticed that the Apple Composite AV Cable appears to have two versions: MB129LL/A and MB129LL/B. The MB129LL/A is described as just "Apple Composite AV Cable" While the MB129LL/B is described as just "Apple Composite AV Cable W/COLOR DISPLAY". Amazon even has the two versions: MB129LL/A and MB129LL/B The Apple store appears to be selling the MB129LL/B version. Does anyone in Canada know where to buy one on-line for a reasonable price (Canadian Apple store does not carry the item at all)? Best Buy Canada carries the MB129LL/A version. Does anyone know what the actual difference is between the MB129LL/A and MB129LL/B?
