It's frustrating that going with 8 gigs of memory is so price prohibitive right now. And it won't work in my 15" MBP. I get the pic below just when I have my default apps open that I need for work. As soon as I open a lot of tabs in Safari, or when I'm doing something else, forget about it - this thing is dog slow. Frustrating! Oh well... here's to looking forward to the next MacBook Pro update...
