Anyway, here's my take on Server 2003 vs. 2008:
You can do a lot with 03, and certainly much of the platform functionality has been backported or just not updated in 08 (WDS, WSUS, Sharepoint 3, Microsoft Deployment, Exchange 2007, etc.) but 08 just has a much slicker interface, and several of those components integrate nicely into the new management console. It's a hard sell to get someone to upgrade at the present time if most of their workstation fleet is XP, but purchasers of new hardware shouldn't get 2003 anymore. Overall, it's easier to deploy, manage, and maintain 2008. Hyper-V is one of the most unique features (even though it's not RTM - YET!), and I can see a lot of merit to it.
