Apple has just reduced the price of the lowest tier of refurbished MacBook Air to $699](Refurbished MacBook Air 1.4 GHz Intel Core 2 Duo - Apple) — I’ve just seen it pop up on a couple news sites. One would think that the option of getting for such a low price what was a year ago an object of envy would make it a no-brainer. But it is the old version of the famously flat laptop, and although it may seem superfluous to point this out, I feel I should warn our readers that to take advantage of this deal is to buy yourself some grief.This version of the MacBook Air debuted in October 2010, and it has a Core2 Duo processor that has roots going back to 2008 and before. It was outdated when it first showed up, and it’s a dog now.
