Why buy new, if what you have meets your needs, eventually, we need to get a second computer here, but I honestly have never cared if I have the absolute latest, as long as it does what I need ti to do and is going to do so for some time to come, why worry about it? I almost always buy one generation older at MacMall, as when the new generation of any Apple product comes out, they sell the previous one at a substantial discount, for example I got my wireless Mighty Mouse for $19 as I recall and the only difference that I could find was that they changed the color of the side buttons.
