Yes, I agree that even if every other component is put into sleep, the memory would still drains the energy; and no matter how slow that process is, if not recharged, there will be a time the battery finally runs out.

But the thing is, it looks like there is not much difference between a single stick of 1GB RAM and a single stick of 2GB RAM in terms of the power consumption rate. This is indicated in this article http://www.buildcomputers.net/power-consumption-of-pc-compon... ; well, it's for desktop RAM but I would assume tablet RAM will behave similarly, as seen from other tablets that upgraded from 1GB to 2GB.

From the user experience perspective, if there is no noticeable penalty -- the physical size and the power consumption are the same for 1GB and 2GB RAM, then why not just put in the one with larger capacity, for a better user experience? (and possibly much better for those of heavy multitasking tendency).

Is that because 2GB is much more expensive than 1GB, for tablet RAM? I could not find any tablet RAM price information through googling -- it's not for retail to individual consumer but only sold in batch to manufacturers...
