World's fastest Laptop, running Windows Vista

If someone asked you which is the fastest laptop that would run Windows Vista, what would you say?? How would you impress a friend with your tech knowledge( pseudo though) if you fumble answering this?

Well, I would have said DELL XPS range of laptops, it is supposed to the "High performance" laptops that dell offers and also it looks kind of sleek too (one of my friends who was also my project mate, had one).

I guess most of us would guess Sony ,Toshiba or HP.

But can you guess the winner ?? , well you will be surprised by the Google search result for "fastest laptop to run vista"(like me) :
