The chaps at CNET in the US gave a fair outline of the PC v Mac debate on the show the Real Deal (178) http://cnettv.cnet.com/?tag=hdr;snav

It's over 30 mins long as a programme, but the relevant bit is only 5 - 10 mins.


EDIT: just tried this link and it takes you to the home page, you will have to search for the relevant podcast.
