I think the MacBook Neo presents a dilemma, what is the worth of really good physical construction of a laptop if the computing capabilities inside may not be as valuable over the long haul? I think people considering buying the Neo need to consider how they will feel if after just a few years they will want to replace it with a more performant computer. At the root of this is the question of whether or not one thinks $599 is a lot of money.
Most likely what the Neo is really about for Apple is increasing cash flow from Macs. Previous Macs tend to be useful well beyond five years after release, which makes it hard for Apple to convince people to buy their new models. I think Apple hopes that today’s Neo owner will replace their Neo next year or the year later at the latest.
