Actually the install process is exactly the same since you're having to do a clean install.
BTW, I love your moniker... Mr. Intuition! Sounds like you should have a radio show or cable TV program!
I am assuming you don't have the Windows 7 yet.
- Do you want to purchase from a local supplier in your area?
- Do you want to purchase online?
- Do you want to have support from Microsoft?
If there is a Frys Electronics in your area, go there, they have very good prices on Windows 7.
If you want to purchase online then I would use either Newegg.com or Amazon.com.
Both will give you free shipping!
