svdl, thank you. I don't use laptops at all (with kids, laptops are dangerous as in the children want to play with them while taking a bath or such and it just doesn't work out). Laptops tend to be a lot pickier and harder to deal with. My husband and I build and work primarily on desk top systems and have not run into any problems. XP on the desktop actually refused to install some of the kids games and that is when I decided we'd stick with Win2000. Personally, as far as all the memory (RAM) debates go, I'd wait until CL develops a fix for the P6 Memory Bug before I did any upgarding or anything else. It seems to not really matter what you are running or how much RAM you have...you still catch the bug once in a while.
