Notebook/Laptop: Which Windows Server 2008 version is the best?
Actually there are three major Windows Server 2008 versions which are considerable to be used as a desktop operating system on a notebook/laptop or PC: Web, Standard, Enterprise, and the Datacenter edition. If you intend to use one of these server operating systems on your workstation resp. desktop, you should choose the Enterprise edition as it offers all Enterprise features but still can be slimmed down to a Standard/Web edition feature set as you may not need many Enterprise Server features (and server features in general). But in the case you may wish to try them, you will still have the opportunity to add them to your current setup. Under no circumstances you should install the Datacenter edition as it is optimized for server virtualization. Therefore it has a corresponding kernel which is optimized for this kind of tasks. But this kernel will definitely not fit the needs of any notebook/laptop as they have no corresponding hardware (hardware virtualization enabled CPU) characteristics. Even if you have a modern virtualization capable CPU, the corresponding features are disabled on all (or most?) notebook/laptop CPUs. So the kernel will slow down your system. On a workstation CPU the corresponding hardware virtualization features may be enabled...
For further information you should look at this site where you can find benchmarks, screenshots, tuning tips, and last but not least "...to desktop operating system conversion tips" for users intending to use Windows Server 2008 as their desktop OS.
However, in this context I have tried Windows Server 2008 Enterprise x64 for a few days and went (maybe I should say "run!" :) back to Windows Vista Business x64 as it is the best Windows operating system for me at the moment.
