Actually, 4 gb are enough for any operating system. Having more is just a waste of money and the dimostration that you are rich and wasting 'em.
Memory is what, $10/GB? Even if you only use the extra memory 5% of the time, it's worth an extra $50 or whatever. Especially on Vista/7 where you have Superfetch to make up for the fact that Windows decided it was a good idea to constantly close your apps every time you want to close a window, so you might launch programs like browsers a hundred of times a day.
