As with my previous Apple product-related blog post, this update too can be summed up as another incremental update. It doesn’t have a better screen, its a little faster, battery life is the same and it doesn’t do anything significantly different from its predecessor (or even its predecessor).
The most revolutionary change in the iPad world was the inclusion of the Retina display - that was cool. And the change to a Lightning connector - really reduced the number of inventory parts required. Again, this is a humdrum update which you would be best to avoid completely if you had the iPad 4, or if you had someone to give your iPad 3 to in order to get homogeneity across connectors.
