I think it is a set PPI or above, since 'retina' was marketed as the point at which the eye couldn't detect the pixels. Presumably anything more dense would be considered the same. Since the 10" is a so-called retina display, it stands to reason that a 7" display with the same resolution also is retina.

Okay, that makes sense. I take it the screen sizes are also close enough in size that font size difference problems will be minimized? I've been wondering how Apple is going to respond to the need to sell better hardware while keeping their design targets minimal, which IRC is a major developer selling point for them in comparison to Android.

Well, in this respect it's the same situation the old iPad mini was in a year ago, and I haven't heard of major problems.
