It is quite common for people to be excited about something right after purchase only to neglect it later on. This certainly happens with some tablets as some realize that they prefer using their phones or their laptops.
If this happened to you, then consider doing something useful with your unit anyway. You could repurpose this device as a bedside digital clock, photo frame, ebook reader, and so on. You could also just give it away to someone who might need it.
If you prefer getting cash out of this device, then head to iPad buy back stores and trade it in. You might get a few hundred dollars for it within minutes. You could also use this value to reduce the purchase price of something else that you have your eye on.
Whatever you decide, do it quickly while your tablet still have good value.
