> They haven't even imagined somebody would want more than 2GB at this point.
correct. all these SoCs are targetted at tablets, tablets, tablets, tablets, tablets aaand... tablets. why would you *ever* want to run more than one program on... a tablet? that's the logic. any fabless semi company that pays MORE MONEY for the DDR3 Hard macros that can address more than 2GB ends up... not being competitive!
... or so they believe. and it's too much money to throw away on a risk like that ($USD 30 *MILLION* minimum for most of these companies).
about the only way to convince them is to steer fabless semi companies towards "chromebooks". *all* x86-based chromebooks can do 8GB RAM... none of the ARM-based ones can. chromebooks are a large market, therefore they *MIGHT* be convinced of the extra costs.
