And with regards to workstation or server. Workstation is aimed at developers. It has some nice API hooks to control the VMs. You can create something in Visual Studio and instantly push it to a VM. You can create multiple snapshots of a VM and make changes, revert to a selected snapshot. Collaboration (share VMs) etc. You can even record everything a VM does and replay it (6.0). These things aren't in server.
ESX is aimed at enterprises, it has neat things like VMOTION.
