Hi!!!! I wouldn't worry so much about SP 1. In about the middle of March, Microsoft has plans to automatically download it to your computer in increments. All you should probably worry about is getting your computer ready, Driver and Bios if necessary. Some people have had trouble accepting new Drivers because of a defect in the mechanism that loads it. Somebody said SP1 corrects over 500 bugs, that should make operations in the brain for your computer easier. Take it as it comes, one problem at a time----
