Sweet. What made you decide to upgrade the RAM? Not sure how much I actually need the extra 1GB using XP but I turn the page file off with 2GB in place so it helps for that. Negatives to bear in mind is that hibernation will use 2GB of disk space instead of 1GB so will take roughly twice as long to go into and come out of hibernation if you use it. It also uses a touch more battery with the extra RAM although it may only shed a couple of minutes off the battery life if you even notice it.
