When Apple first released their patented Retina Display on the iPhone 4, it was considered a game changer. Although the screens on the iPhone and iPod Touch were certainly clear in the past, this brought a new type of resolution to the smartphone world for people to utilize. Since then, Apple has slowly started creating Retina displays for people who are looking to relieve their eyes while using different products.

As Apple expands its lineup, the question is, how much of a difference does it make for the standard user? Since launching with the iPhone and iPod Touch, Apple has expanded it to the iPad and the Macbook Pro. The iPad Mini has yet to receive the Retina Display, despite the public outcry for it to be released.

Switching back and forth from a Retina to a non-Retina iPad and Macbook definitely shows a difference, but studies have shown that the average user might not be able to tell the difference if they are not presented both options. When given the option, people always gravitate towards the Retina Display, but there are a few drawbacks to the higher resolution screens.

Apple has said one of the reasons why Retina has not appeared on more mobile devices is the fact that it eats up too much battery. With more pixels being utilized with the sharper screen, a bigger batter is needed. If the company adds too big of a battery, the mobile device becomes less mobile for the average user.

Cost is another big factor, both for Apple and the consumer. While a sharper screen is nice, is it worthy of the upgrade? Apple introduced the iPad Mini at $329, and Macbooks and Macbook Airs can be purchased for under $1000. Add Retina Displays to all of those options, and a few hundred dollars will be tacked onto the price as well.

At some point, industry standards and public demand for Retina Displays will for Apple to include it on nearly all of their screens. For now though, most consumers will be just find with standard screens that are provided on entry level Apple products.
