The reason it seems that windows vista is using a lot of RAM is that is keeps running programs through it. By doing this when you load up an app it loads up right away instead of like XP which empties the RAM so when when you open something there is a delay(sometimes it takes long) to find the app and load it up. windows vista RAM usage is more efficient than XP.
You can look it up if you want to. I here "SO" many people talking about this and I just wanted people to know what is actually going on.
