I primarily use VMware for virtualization and simulations. I rarely use more than 60% of the 16GB as well
Well, I run an enterprise class software platform fully operated in VMWARE and I would need 18 GB RAM to start them all.
For now, I have always to suspend one and to start another, annoying.
But with SSD SATA3 disks it is incredible fast, so fast that I am afraid my customers will be later on complaining that in the production the applications would not run so smooth as in my virtual machines .

I was not even running enterprise grade VMware. Only Workstation. If I have 16GB of memory, I would be able to use it almost all.
Win 7 64-bit + Background Process + VMware (2GB)
Mac OS X Lion Server (2 - 4GB)
Windows 8 Preview (1GB)
OpenSUSE Linux (1GB)
Windows Server 2008 32bit (1GB)
Windows Server 2008 R2 64bit (2 - 4GB)
Windows 7 (1GB)
Windows Server 2003 R2 (512MB)
Windows XP (256MB)
Since I do not have a need to run simulation for environment, 8GB is just great for practicing labs for Server OS, software as I do not need to up all VM at the same time.
Does someone post helps you? Give them a kudos as a reward, as they will do better to improve
Mark it as solved if the solution works for you, so it could be reference for others in the future

So there is a consensus that having plenty of RAM is most justified by the use of virtualization technology!

The problem you run into, especially if you purchased a W510 or W520 with 16GB of mermory, is the cost to move to 32GB. For most people the cost IS NOT justified at this time.

Yes, working fine.
I just broke my two elitebooks, and now every 8GB memory chips are on my new Thinkpad w520. 32GB is lot of ram... even for vmware hosting...

>>And I haven't managed to use more than 60% of my 16GB RAM yet.
>>What programs are you all running?
I am running computational fluid dynamics codes on my W520. I run very small problems to test my code and 16 GB is not enough. I use a Cray XE6 with 43,000 cores and 85TB of RAM to run my code on real problems. When a Thinkpad gets this capability I will consider it to have enough memory. Before anyone laughs at this I will point out that my W520 has 40 times the processing power and 16 times the memory of the Cray YMP I used back in 1991-1993. Historically for me, it takes only 20 years to see the power of a current Cray supercomputer make it into a home computer for under 2 grand. I chuckle everytime I power up my W520 and think back 20 years.

For the record, we just got a pair of 8GB Corsair sticks for an X220. For kicks, I first tried putting them in my 2 year old W510 (i7-820QM 1.73 GHz quad core), and they work! The machine correctly reported 24 GB (2x8GB + the existing 2x4GB) in the BIOS, in memtest, and in Ubuntu. So it certainly looks like this machine unofficially supports 32GB. This is a pleasant surprise. I use it for neural data analysis, and at times use up to 14GB or so at a time, so 16GB is enough for me, at least for now.
The exact model number of the Corsair RAM is CMSO16GX3M2A1333C9. It's a 2x8GB package. I got it for CAD$140 at NCIX, after pricematching at http://pricebat.ca:
