The most intense thing I do is work with Aperture. I'm sure it'll be fine now but what about in 3 more years after the next few OS updates? I know that nobody knows, but I'm sure this has come up with different Macs. Is 8GB a must to "future proof?" I don't want to have to spend an extra few hundred on RAM. If that's the case, I'll just get the Pro and it'll be upgradeable. What do you think?
