Pros: cool processing and looks . inbuilt protection from virus, firewall. fast and secure
Cons: lots of security creates headech

I am using Windows XP PRO SP2 from last year and yes it is really fast and secure than previous versions:-
The inbuilt protection from virus, firewall, and security center is worth it...
I bought this product because of its cool processing and looks .
The security and the speed which it gives and a crisp colourfull display i love the most.
But too much security often create surfing on net a horrible experience i.e. too much warning, Pop-up stoppage etc.
