Alright so here's the deal. The 13 inch MBP Core i5 and i7 have identical HDD and SSD upgrades (minus the 500gb HDD for the Core i7). Identical manufacturer, model, and capacities. BUT Each upgrade costs $50 MORE on the i5 than the i7. WTF? How is this even remotely legit? You are paying for THE SAME upgrade! Am I missing something?
