    Note than in an era of auto-polarity-detecting switches crossover cables to go from switch to switch are no longer always necessary :)

    Yes, but you can you guanentee that auto-polarity mode will be supported/enabled on that device? no you can't so there for its better to learn both T568 A&B so that you can make them if need arises.
