I just bought a new 2011 MacBook Pro (specs in sig). I've been noticing this thing eats memory. Just a few minutes ago I was copying a 7GB file from my OS X desktop to my Windows 7 Ultimate desktop running in Parallels. About halfway through the computer froze up and had to be forced restarted. With four gigs of RAM this seems to be a problem, or am I just setting my goals too high? Attached is a screenshot of iStat Pro after my computer had been running for only 1 hour. The only things running were Chrome and Transmission. Is this normal? When the computer froze earlier, I believe it had 100MB of "free" memory and 190k page ins with 58k page outs. I am thinking about buying 8GBs of ram, but I didn't think it should be this needed.
