Im thinking about buying new device hand held have older kindle tring to get advice wich is best thank you

Depends. Which carrier are you using? What's your price range? Do you want to be able to root it or install a custom OS? (I can help w/ those if you want) What screen size do you want? Phone or tablet? Is it primarily for DF?

Im computer stupid by carrier I think at&t using 7 inch kindle will be for df with my kindle get no trees and such graphics may want to go to larger so can see better going to try grandsons ipad its large see how it is when they visit spend 300 to 500 dollars when I get one thank you
