With the recent release of new MacBook Air models, B&H is clearing out the past generation and has the entry-level MacBook Air for $799 (reg. $999). Of course, the new entry-level model is only $849 (thanks to a $100 price drop on the MSRP when Apple launched the new models and B&H’s sale prices).
I actually have the model that is one year older than this model on clearance and have been very happy with its performance. I generally use it for travel and run Lightroom on it with no problems. Check it out here at B&H Photo.
