It was confusing to me that you were thinking from the corporation's viewpoint! That makes it way more complicated than necessary. a) Apple constantly toots their horn about putting user experience ahead of anything else. b) Apple has lot of money. c) There are lot of products on the market - phones, tablets that sell for both premium and no-profit, that have 2GB RAM. d) Apple sells the iPad at premium price points e) I am certainly not the only one that would benefit from more RAM. I bet lot of people will benefit from having more memory for their "post PC" device.
As a user I don't have to care what Apple has to do to get the RAM up - renegotiate with their vendors, improve battery life, sell a different SKU with more RAM and $16 more in price, eat up the cost as a price to pay for user experience etc. You kept explaining why they couldn't do it when others have been there and done that.
Frankly even viewed 100% from Apple's standpoint, none of your arguments are very convincing, especially so if you look at what actually is involved in 1GB of additional RAM and when even lower priced devices have it.
