That would remind me on the transition form iPad 1 to iPad 2.
The gain was minor; the cameras quite crap.
The adult in me said: wait, the increase is not worth, skip that one, get the next.
The child in me was too noisy so the adult in me picked his credit card and made the child in me silent while playing with the new iPad 2.
But seriously: the memory constrains on iPad 1 was just too much. I often run in terminated apps because of memory. Plus I really like the smart covers.
I voted "no retina, no sales", but that's more a statement. Sure I get one.
