The 9.7-inch 2048 x 1536 Retina screen is one of the best (or I can go so far as saying the best) looking of any tablet out on the market today. Much like the third-generation iPad, text, pictures, books, magazines or whatever that’s optimized for the Retina screen look absolutely gorgeous. When you compare this to the iPad mini or the iPad 2, the difference in screen quality and resolution is very obvious. On the iPad mini, reading some Newsstand Apps was not a good experience because of the blurry, pixelated text. I had no such issue with the Retina display.
If you are going to do some work on the go, such as graphics, photos, reading and writing, I would highly consider the larger iPad over the Mini. The full-size iPad has substituted many tasks that I would do on my laptop because of the more than adequate screen size and display quality. If making a decision between this, the iPad mini, or any tablet, the iPad with Retina Display would be the most sensible choice.
