Actuallly, it would be like Windows XP Professional less the ability to join a domain. Exactly, you cant actually call MCE XP Pro. One of the main functions of pro is that it can join a domain. MCE with out the Media Center plugin is really just a beefy home version. I hate how people say MCE is pro, if that was the case I wouldnt have spent the last 2 weeks trying to combine the two. MCE is NOT PRO and shouldnt be called pro no matter what the install says.
