everybody who thinks the huge memory footprint of vista is a bad thing, should seriously read this article: http://www.anandtech.com/systems/showdoc.aspx?i=2917&p=4 it explains very nicely why it is not a bad thing, and on the contrary helps make vista faster (if there is enough memory) the bottom line is, that vista has sophisticated algorithms that try to guess what software you are trying to run at a certain time and preload that software an all its used libraries in the memory. i personally never understood why people buy 1GB of memory and then dont want the OS to use it. thats what you bought it for, remember? If you start applications vista flushes the preloaded stuff to the HDD and makes way for your applications. as you can see theres really nothing bad here. my point is that vista uses the available memory much better than xp did, and yes, maybe vista needs more ram to do its magic, but its not like you wont benefit from it. if you dont want to upgrade your system now, install vista after you did at some point in the future.
