Tomorrow I will buy a 2nd hand iPad with Retina Display. But I do not have an idea how I can distinguish it from ipad 2. I know retina display is a very significant difference for experienced users. However I have never used an ipad 2 or ipad 1 so I cannot understand the difference.
What is the best way to distinguish two of them? It seems like there does not exist any logo like ipad 2 or ipad with retina display on the back of the device. Is there a way to understand it from settings menu or somewhere else?
Regards
