Exactly my point! And first of all, the Air is more advanced than the cMBP. How the hell can Apple get away with selling it for more than the latest models?
The Retina is always on sale for like $1199 plus Student discounts. Nobody in their right mind should be coughing up $1049 for a cMBP in 2015! Ethernet and a SuperDrive are invalid excuses in 2015, with the speed and reliability of Wi-Fi, Mobile Hotspots available and the fact that we get all of our content digitally. You can get a Desktop Tower with a CD/DVD drive if you want, or just buy any random $20 Portable off of Amazon.
No modern company should be able to get away with selling 5 year old hardware (Yes, hardware, not the 3rd gen Intel update in 2012), for over $1000. I know it goes on sale for $899 here and there, but the Air is on sale today at Best Buy for $849 and I would take that over the cMBP in a heartbeat! The SSD would make up for the 1.6ghz speed of the Air.
