I'm toying with the idea of buying the new MacBook Pro base model. For the more technically inclined- does it make sense for me to upgrade the RAM and processor? I would use this mostly for general internet dicking around, light gaming & light photo/video work. I don't mind ponying up the extra dough if it means I can squeeze an extra year or two of life out of the thing, but if the upgrades are wholly unnecessary I'd obviously like to save the cash. Thanks!
