Hi All, A very quick question - am looking to upgrade my early-2011 15 inch macbook pro memory from 4gb.... Based on the page-outs vs page-ins I have read about, I am in need of some more memory (although not desperately). 8gb is now very cheap from Crucial, but the 16gb upgrade is also looking very cheap (at least, compared to when I looked last year!!!). So, does anyone think it's worth going for the 16gb upgrade? Will I notice any difference? Cheers!
