A few months back I wrote an editorial for the Windows Vista Offical Magazine about the newly released version of Media Center found in Windows Vista (if you read that magazine my bit starts on page 64 in this months editon). I don't think I would get away with posting what I wrote here since I don't own the copyright anymore. However they did post some content from it free online. I was asked to come up with a list of Q&A questions so here is my current pick of 9 questions someone new to Media Center would have buying Vista.
