I have a 13" Air 2010 with the 128 toshiba drive. I am thinking of getting the 799 mini with i7 upgrade and swapping in Air drive as a boot drive and getting the owc aura 180 for my air. The point being that I would increase drive capacity by 50% in the Air and get a much faster drive- according to barefeats- and get a much faster boot drive for the new mini at a big savings over the mac offering. Any thoughts? is it worth the $100 for the I7? Is this doable?
