Joe, this is the most unprofessional and most laughable piece of evidents presented on this topic. paging has been a piece of technology used in computers since ram and hdd's have been working together and being that again as stated in other viable and reliable sources yet a home.mac.com page. unix/bsd/linux handle ram differently and in regards to paging do it more efficiently. beyong music producing such as what kevin and jerry ram is "NOT" essential enough at this time to be purchased in such a waisteful manner.
