Boy, this thread is filled with haters.
What do you do with 16GB? Plenty! For one thing, Virtual Machines.
On my current MBP (2.66 i7 2010 8GB) I run VMWare ESX (under Fusion) and within that I have several very intensive virtual machines. I get left with under 500 Megs after I have everything up and running.
This allows me to do customer demonstrations of a very complex setup that would normally require up to eight pieces of equipment... all in a little 15 inch MBP.
So anyway, quit the hating. It's awesome that we can run this much RAM. Thanks for posting the info guys!
+1 I run something very similar and I couldn't agree more!
