Doesn't swap adversely impact the longevity of one's solid state drive?
Not being facetious -- if you operate entirely within RAM (as if you had disabled swap), then it won't really be used much.
This is one reason I went with an 8Gb RAM Mac recently. If I go into swap territory occasionally it's not really a big issue. As yet as a terminal node, which is what it really is, I barely ever touch swap even with a ton of things open.
