Well I have been running Server 2008 on my llaptop in order to run MOSS directly from my laptop. This has worked out great and I will post all about it later.
One nice thing about Server 2008 is the Desktop Experiance. It allws Server to look just like Vista for the most part.
One annoying thing, however, was the thumbnail view for folders are turned off. If you are using 2008 as your main OS you may want turn this on.
It is very east to do. Go to Folder Options on any Explorer window and click view. Then uncheck the item that reads "Always Show Icons, Never Show Thumbnails."
