I have been changing my mind for the past few days on which one I will be getting and what is best for me. On one hand I really do not need more than 256GB SDD and was planing to just get that with the 1.3 BTO but the price is so close to the 512/1.2 model I might as well get that one. I really want the the 1.3 BTO after reading some of the review that should increase the performance quite a bit. I really do not need 512 sdd. I plan to resale this mac once the newer version comes out next year so was thinking the bigger 512 ssd has better resale value. I am very confused and can not make up my mind what do you guys think I should do if you were me ? thanks
