How to buy a used ipad
Determine the storage capacity, display capabilities, ipad model, and mobile connectivity (currently 3 g or 4 g, third generation or fourth).
Figure out what size ipad you want. The earlier versions of the ipad are thicker and heavier than the new ipad, so, if you're looking for something lighter, the ipad air might be a better fit for you.
If you need a powerful ipad for professional stuff, the ipad pro 12. 9 " or 9.7 " is the perfect one for you.
