SE hyper-V included, plus 1 virtual instance, terminal server ,network access protection, and CALs. EE plus 4 virtual instance, 32-bit 32GB 64-bit 2TB, CPUs 8, cluster service yes 16 nodes per cluster. DE unlimited number of OS, CPUs 64, hot swap ram and cpus yes.

Some of the new features of server 2008 are server core, PowerShell, and virtualization.
Server core is a minimal installation option provides an environment for running the server roles. Some of the roles are DHCP server, DNS server, file services, and print server. The three ways you can benefit from the installation are by reducing the software maintenance required, reducing the management required, and reducing the attack surface. Virtualization provides software infrastructure and basic management tools that you can use to create and manage a virtualized server computing environment.
This can help by Reduce the costs of operating and maintaining physical servers by increasing your hardware utilization, and Improve server availability without using as many physical computers. And PowerShell is Microsoft’s task automation framework, consists of command-line, and scripting language. It provides access to COM and WMI. Read-only domain controller is a new type of that organization can easily deploy a domain in locations where physical security cannot be guaranteed. RODC will improve security, faster logon time, and a more efficient access to resources on the network.
