I may possibly sell my iPad. I have a third generation iPad (4G, 64gb). I also have a Smart Cover, iPad keyboard, and power cord that comes with it. Right now I am torn on whether to sell it. However, I do not feel that I am able to get the full productivity that I need from my iPad. Thus, I mainly use it to check email and the Internet. If I were to sell it, can someone tell me the best way of going about it?
