This is a slippery slope - regardless of whether or not RAM optimizers are beneficial, *I* found that all they do is make me fixate on how much RAM I have free. I actually own licences for three shareware RAM optimizers (comments about fools and their money will be, politely, chuckled at) and have at least two other apps that feature RAM optimizer components, but I don't use any of them anymore. I *think*, but cannot prove, that these apps have little effect on the functioning of my system and just serve to make me obsess about the difference between 512MB free RAM and 100MB free RAM. I haven't actually observed much difference in performance no matter how much RAM I have free. Now, that said, I can imagine that if I didn't have a lot of RAM, a RAM optimizer might actually be very useful (certainly when I was running Win98SE with 128MB RAM I *thought* it made a big difference). With a gig of RAM there doesn't seem to me to be any benefit (my daily computer usage sees me running Xara Xtreme Pro, PhotoShop Pro, Office Professional 2003 - the only thing I don't run often is Publisher, Maxthon, ESRI ArcGis, etc.)...
