I hope not. My iPad with 256MB of RAM and a relatively slow ARM processor feels snappier than my laptop with 2GB and a dual-core 64-bit Intel processor, partly due to the consistency: I never know, on the latter, whether an application will respond quickly (because it is active in memory), or slowly (because it isn't). If I could use iPhone OS's model on my laptop-- with more freedom due to the increased memory, but still omitting swap in favor of automatic saving/memory management-- I would.
though, who knows, maybe the declining cost of RAM will solve this problem for PCs, and eventually phones.
