Well, the company i work for uses Xp Pro at there work stations. Everyday, we have a different workstation that crashes. Whether it is because of the user, or XP Pro itself, I personally think XP stinks as an OS. So when the company gave me a copy of Server 2003. I couldnt pass it up. It ran for 2 years straight before R2 came out. They also gave me a copy of the full Server 2003 R2. I have had R2 running since the company gave it to me. it has as of yet to cause me any grief. I think Server 2003 and R2 are the most stable OSes out there. I can run alot of the same stuff as XP with out a problem.
