This is one of the biggest reasons for me, personally. It is such an inexpensive difference in overall cost versus the benefits of having that headroom. Plus I am sitting at ~26gb used memory right now. I tend to give my VM's a nice big 8-12GB chunk of ram depending on what I am doing too, so it is almost like I have two machines in one. The disks and data pipelines on these new machines are so fast though that I do wonder if the RAM's responsibility has shifted towards being a giant CPU cache and the disk has likewise shifted into a point where it performs more like RAM.
