An Apple refurb Pro costs less than the Air when similarly configured. Same warranty.
Also, $1799 is for the quad-core model. The base dual-core model is $1299 with 128 GB SSD, and it's $1499 for the 256. However, for the refurb, it's only $1269, which is $130 less than the Air.
Last week I would have agreed. But I’m thinking then Air might have 802.11ac Wave 2. To be confirmed, but twice the wifi bandwidth vs the modest processor horsepower (I think?) it’s suddently not so cut and dry.
