What matters whether they have improved something or not. > but for $40, I can still conclude that it's worth No, you have to judge the claimed improvements based on their merit alone, not on the price attached to them. When you identify the merits, you can decide whether they are worth the price asked, but from knowing the price, you cannot deduce how big the merits possibly are, thats a fallacy. As somebody who is using XP and 7 simultaneously for years now, I honestly do not see why any random end user should invest effort to upgrade to 7. They can just wait till their XP machines break and then just get whatever is preinstalled at the new machine they buy.
