Is a Retina iPad Mini really so desirable?

The title says it all. What do you think?

Personally, I don't think it would be that big of a deal if it didn't get a super pixel dense display. Barring the fact that the competition is doing the high dpi thing, I don't think there are really that many good reasons to push them. I feel like I'd rather have something last a super long time on battery. Apple has never really been shy about keeping the resolution down on it's MacBook Air line to save battery, why not on the iPad?
