I wonder if the Ipod Touch 5 or Iphone 5 with a bigger screen should be enough to replace the Ipad 7 inch. A 7 inch Ipad with 8GB of memory space limit the amount of downloading high resolution content. But a 8GB of memory space for the Ipod Touch 5 can download more content at lower resolution. Plus it fit better in the pocket and should be less expensive than a Ipad 7 inch.
I prefer a Ipod Touch 5 with a 5 inch screen then a Ipad 7 inch.
