While your iPad was designed to withstand a lot of everyday abuse, most users agree that it’s a good idea to actually have a case for it. When you protect your iPad with a case, you’re actually making a very wise investment. In addition to keeping it in excellent condition, many cases will offer protection from some of the elements, including rain and dust and various particles. Also, if you’re tossing your iPad into your knapsack or suitcase, having it in a case prevents surface scratching and wear. Since many iPad owners will often trade in their old iPad when a new model comes out, the better the condition it is in, the more money that will be offered for the trade-in value.
