I certainly won't argue with you regarding battery life being affected by RAM but I will share a couple of things with you.

* Yes, the CPU does have to stop for a RAM "refresh" every n number of cycles. RAM is volatile, meaning that it cannot hold a value for very long. A RAM refresh is where a current is sent through the RAM that allows it to hold its state. However, this is done to all the RAM every time, so the amount of "used" RAM does not change how long it takes or how much power it uses. Power use is only affected by the total size of RAM (used or not) and the number of writes to RAM.
* Just because the OS is reserving that much does not mean it is using that much.
* Obviously the amount of RAM we have now will not be enough in the future. But I seriously expect that by the time we reach that point, the Touch Pro will be obsolete anyway.
