MS Windows XP Media Edition

I am looking for info on MS XP Media Cemter edition. I am looking at getting a new PC. I know that Media edition is NOT an OS that is capable of being put onto a networked Domain since it does not have the necessary funcationality of authenticating with a Domain Server “(such as Server 2003). However, since I need to VPN into work using Cisco VPN, I am wondering if there are issues with attempting to connect to the domain using such a method with this OS or if this will not work either due to the limitations of this OS. My gut instinct is to stick with XP Pro for this but DO like some of the multi-media functionaltiy of this new OS. does anyone have any thoughts on this subject? Thanks!
