Why Should I Upgrade From Windows XP?
Windows XP is inherently more risky even now, and when Microsoft stops supporting the venerable OS this April, (April 8th, 2014) your PC will be virtually defenseless.

Aero Snap & File History
Aero Snap makes maximizing, minimizing, and organizing windows as simple as dragging them to the edge of the display. File History (Windows 8) scans your files every hour and stores copies of the incremental changes over time.
Your old hardware has a limited life span. It will eventually need to be replaced, and just like an older car, parts become harder to find and more expensive ($$$).
