Summarize this article:

If you want to part ways with your iPad so you can exchange or upgrade it for another electronic device, a trade-in program may be in sync with your plan. A number of companies allow you to trade in your iPad for credit, cash, or a new gadget.  When deciding which trade-in program is best for you, go to the websites of companies offering the trade-in program to find out how they assess devices, how they offer compensation, and if it will meet your specific requirements. Compare similar used models sold online for a ballpark figure of how much you can expect to get from these companies. If your goal is to have extra cash on hand, a trade-in program wherein you receive a gift certificate for a retailer is not ideal. However, if you simply want to get rid of your device without much ado and still get something in exchange, go for the trade-in. Apple also allows you to trade in your iPad for a gift card. Recycling can either be done online or at an Apple store. To find out more, check out this portion of Apple's website.

Summary:
Consider a trade-in. Give recycling a thought.
