I have just upgraded my system from xp to vista. My son says it very slow and bad operating system. He was suggesting to go for windows 7. He is just a kid but know stuff about computer. But still I thought it would be great if I ask others too about this. How do you compare vista with windows 7? Which one has better performance? So if its good I wanna buy it. How much is the cost of windows 7 OS?
