I am in the process of ordering myself a new Dell.  I have had my Dell for about 10 years now and time to upgrade and have a couple questions for you.  First of all, how do I copy my old hard drive to the new one?  Also the newer models have Windows Vista, I have Windows XP Home, what is the difference between the two and is the Vista as good as the Windows XP?  I am ready to order it today but would like to know the answer to these questions before I make my final decision.  Thank you.
