For the 1099 price point I got the Rev A - 1.8/64GB SSD - which I absolutely love and the price difference was enough for me to go with the original high end rather than the rev B - MacMall does not tax me
and Apple well - does - so that saves me around $100.
But it is an okay deal - if you have the cash the Rev B at 1349 from the refurb store is the way to go - double the hard drive space from the Rev A and a real graphics card.
Best of luck if you are in search of purchasing one
