Care to elaborate on this?
As far as i know, windows Home and Professional edition are exactly the same, apart from advanced networking and other advanced administrative tools. If he just wants to game and use the computer for regular tasks, then Home is more than enough.
ya i also wonder that question, I need to buy an um "legit" copy of xp but not sure to go pro or home. I have pro atm so i dont know what home is like. But i dont want the pc to be worse/slower using home than it would pro.
