Are the details on a retina iPad display lost on people with poor vision?

For pictures and video, the difference is minimal between Retina and non-retina, IMO. For text, the difference is big and obvious but it may not be very obvious or even detectable for someone with poor eyesight. If she has trouble reading small print, then I'd bet that the iPad Mini or even an iPad 2 would be fine.

For me the choice is different - my 71 year old Mom still has the sharpest vision in the family and I'm trying to find a way not to buy an iPad 3. At least the iPad 4 makes that decision easier: refurb iPad 3!
