First we should debunk the "Retina" Myth.
Apple has a brilliant marketing strategy that Steve Jobs created many years ago, as only he could do. Here's how it goes: take an existing technology, give it a clever and compelling new name, then sell that name to the public as something so special that it's irresistible. Appeal to "the dreamers" give the masses something to make them feel special.
Having already created a cult like following of worshipers to hang on his every word, they'd embrace whatever he gave them as gospel, and spread the word. It was a brilliant and time tested way then, and remains so now.
Example:
Apple decides to use WiFi.
Jobs renames it "AirPort" then hypes it & sells it to the masses during a keynote speech. Suddenly even the otherwise intelligent tech-savy users get all excited having heard from their hero, and it's now something special.
iThis, iThat,
Time Machine
Time Capsule
AirPort Express Base Station
AirPort Extreme Base Station... Oh WOW!
And now... *drum roll* ... RETINA !
See? You get the picture. Jobs was nothing if not the worlds best salesman. Just look at all the success he created. Look at the massive revenue & ultra high margins generated by convincing people he had the "Magic"... and he did!
Fast forward to "Retina" his last big thing.
Nothing more that a fancy name for a high resolution IPS display, he whipped everyone into a buying frenzy convincing them that unless it was a Magical Retina display, it was nothing special.
All you have to do is read the forums here to see all the posts created by the worshipers saying things like once you've gone Retina, there's no going back. It's an amazing yet time tested phenomenon. A brilliant strategy that a super ego, an ultra narssistic guy like Steve could pull off.
He got people salivating for "one more thing". He left them wanting more. To this day it's reflected here over and over ad nauseum.
Better than David Copperfield, Steve Jobs was the ultimate showman, magician, and salesman. Very impressive. Everyone loves it, Hollywood can identify since they sell dreams.
It put Apple on the map forever.
