Macworld blogger Steven Aquino wrote a fascinating piece today on how Apple's Retina display technology has helped him -- a legally blind individual with extremely low vision -- to be able to enjoy Apple's products as if he had no vision limitations at all.
Aquino says that he had used the original iPhone and iPad successfully with their displays set to full brightness, but "seeing my iPhone 4's Retina screen was a total game-changer." The high pixel density -- 326 pixels per inch -- and turning the screen brightness all the way up made it so "even the smallest text was readable, and I was able to spot details in images that were previously indistinguishable."
How much of a difference does a Retina display make to Aquino? "Simply put, I will no longer use an iPhone or iPad that doesn't feature a Retina display. Having used a Retina display, I can't go back to something that makes using my devices that much more difficult." Of course, he admits that having the screen brightness turned all the way up does eat up his battery charge quickly, so much so that a Mophie Powerstation Duo is in his favorite device bag at all times.
