And yet Apple didn't put in the extra memory. I hope you don't think my quick comments here are any sort of serious analysis of the tradeoffs but you should assume that perhaps Apple itself has done that analysis and ended up with a configuration that is different from your expectations for perfectly defensible reasons (from their point of view).

I never said that Apple couldn't put in the extra memory -- I just suggested that there were tradeoffs that suggest why they might not have made that choice. I was trying to add information to the discussion but you seem to want to insist on proving your preference is the right one and that Apple made a mistake (as in the wrong decision for Apple and its customers -- even ones who don't have the same needs as yourself).

Note, I'm not trying to prove that Apple made the right choice -- perhaps it was the wrong one and they could have sold more iPads and had happier customers if they added more memory if they had followed your advice. Maybe they wanted to but couldn't line up sufficient supplies or maybe there wasn't space for the extra memory or maybe they didn't want to eat into their profit margin or …
