Looking into a new 13" or 11" Air. There are so many threads about which display is best and which SSD is faster. I am confused as hell. What should I ask the Apple employee when buying one? Should I go with Samsung display and SSD or Toshiba? Will Apple tell me what I'm getting before paying? I don't want to pay the 10% restock fee because it's not the right one in the box. Please help?
