All I was saying that if this person has to ask where to find Longhorn , then maybe they shouldn't use it? lol I did overstate it a bit, but it should not be used as a primary OS. Its just too buggy at this point, and is very resource heavy because of all the changes in it.XP and 2000 have similar architecture, whereas Longhorn shares little that is similar with either. I would suggest using a multi-partition, and just doodling with it.
