More is never better.
More RAM? Not needed. Again Apple's control of the hardware and software experience means they can maximise performance, efficiency and experience like no other company in the entire world.
A big NO to that comment. People are always howling on this forum that Safari tabs are always reloading, or when you hit the back button, it reloads a web page - even when the page should be cached in memory.
The rather skimpy amount of RAM that you find in iOS devices mean that Apple do things like ignoring web page cache directives. To the annoyance of many a user.
Which is all rather odd, really, given that modern devices are 64-bit (so no address space concerns) and RAM is cheap as chips.
