Not only the ram. The 'sapphire screen' and battery are probably going to be the most expensive pieces of the system. I don't think anyone is complaining that their gorilla glass screen is not durable enough. The highest end phones have less ram most likely because of battery life issues. That ram has to be refreshed, and more of it means more drain on the battery. Not to mention that in android phones, they try to fill up the ram as much as possible to avoid accessing the flash storage after booting since that also drains the battery. The consequence may be longer boot times, if Ubuntu does this also.
