You seem hellbent on defending Apple.
When someone says app reloading, they mean app refreshing (which is essentially a call to all views in an app asking to redraw themselves in addition to updating state). If your argument is constantly about semantics, then you're just being stubborn.
100MB of RAM is not a significant amount. One instance of a UIWebView consumes about 20MB of RAM. And that's before you wrap all the 'Safariness' around it. You're not making relative comparisons (comparing to a Samsung Note doesn't make sense - but comparing to an instance of UIWebView does).
Do you have some strange secret wish that your laptop/netbook (if you own one) only supported, say, 4GB of RAM vs, say 16GB of RAM? Would that make your world a better place? Would apps be 'better' and more 'efficient' if that were true?
There's this assumption that with more RAM application developers write 'worse' code. But often times the increase in RAM required is because the OS and/or the frameworks and APIs associated with that OS are consuming more RAM.
