Ah, so you actually were asking about RAM. That's rare. :-)
In my opinion, it really doesn't matter. It's a lot like processor speed. What really matters is the final experience. We're not talking about a general purpose computer here, but a specific device designed for a specific purpose. A very well written and highly optimized piece of code running on very weak hardware could run circles around poorly written code running on more powerful hardware. Is that the case here? Who knows. What we do have to go on is reports about how the experience is, which is all that really matters, right? :-)
Some examples that might delve into technical details that you might not follow:
- Active polling loop vs event driven. The former would keep the processor from sleeping, consuming excessive battery, wasting CPU time.
- Convoluted algorithms vs. simple optimized algorithms: Wasted CPU time, taking longer to turn pages, wasting RAM for instruction space vs data space.
- Memory leaks: Gradually filling up the RAM making less and less available until the device becomes slow or unstable.
- etc...
As an example. I have a 10 year old hand me down computer that I installed Linux on to use at work which runs circles around my much newer and much more capable system that IT installed Windows and a bunch of their garbage on. Spec-wise the Windows computer should easily beat the Linux computer, but the Linux computer is far more responsive and stable.
