The design of the iPad mini has been a strong talking point. The lack of retina display and the high price tag wasn't something that many favored but the design seemed to satisfy everyone. Apple are really pleased with the shape and materials that were used for the iPad mini and it looks like their next iPad being dubbed the iPad 5 will adopt some of these design traits.
An image leak of the back cover of the next generation iPad looks like it takes most of its design from the iPad mini and it includes a thinner side bezel. These images can be viewed on 9to5Mac. The current iPad design is seen to be the best on the market but not everyone is a fan of larger bezels and it looks like Apple have put measures in place to prevent accidental thumb and finger presses and can now finally downsize the bezel.
We can't take these leaked images as being a definite especially when Apple haven't released an official statement. However, the anodized aluminum design of the iPad mini and the iPhone 5 have been a huge hit with customers so it does make sense that the next generation iPad will follow suit. We will of course have to wait to see what Apple is planning but until then we can all enjoy the latest iPad 4 release with a 128GB of memory.
