I'm finding the 8GB of ram in my rMBP is getting used ridiculously fast whenever I start doing anything. Here are two screenshots, the first is using Safari with only 3 windows open and just a minor flash ad (so clicktoflash would hardly help), and almost HALF my 8GB memory is already gone. I tried using Chrome to compare, and I've got ONE window open with some minor flash, and I've only got 5.3GB left? How are people using 8GB to do any productive work whatsoever when having a 1-4 tabs open on a browser is taking up 30-50% of my memory? This is happening to me w/o iTunes, photoshop, Skype, or anything else whatsoever on at the same time, I don't know what's going on.
