Back to pricing:
For those wanting the 16GB-1TB combo, the price jumps for the 14” MBP are major, even at 3rd party sites. $2099 and $2249!! At Apple, the 15” with that combo is only $1899. So, a $200-350 difference, not $50!
Plus, if one is eligible for the education discount, the price differential is even greater! A 15” 16GB/1TB is only $1,759! And, you get a $150 Apple gift card. $340-490 less than the 14” — or with gift card considered (one could add Apple Care with it later on), $490-640 less! That’s a HUGE price difference, one greatly favoring the 15” MBA!
Furthermore, the 16/512 is only $1599, with that gift card.
Besides, no matter which combo you buy, at Apple, you can also choose, for free, the 70 watt power adapter!
Hence, pricing actually favors the 15” in many cases and for many buyers, along with the other factors!
