To each, his own. I prefer my phone to do what it is supposed to, minimum fuss and fiddle. iPhone wins on this front every time, I don't care what anyone says.
Take it from me, Nexus is a massively hyped flop, but that is just IMHO okay!.
Why would the average user need/want access to the
whole *nix filesystem?. I think Apple are very wise to sandbox the user data... it is very easy for the less knowledgeable user to get entirely lost within a folder hierarchy, unless they are tech savvy, in which case they would failbreak it to do so.
People always seem to forget that the ethos of Apple, is that of simplicity and efficiency. They watch and wait while the rest of the computer/mobile industry makes their mistakes and learns hard lessons by incorporating bleeding-edge tech (AMOLED etc) in their products, and only when they are
completely sure (over years, sometimes), will you see Apple adopt such technologies in their products.
Take it or leave it, I don't really mind either way, and I am sure Apple don't either.
If you want to fiddle and learn *nix, use Android & GNU/Linux.
PS: The whole multitasking point is completely moot; this isn't a Desktop OS, and you can only ever do one thing at a time anyhow. If you want to switch between apps, iPhone OS saves the state of the current app in focus, and then launches the new app. Then when you go back to the other app, it is "defrosted" from it's frozen "freeze-dried" state (all this is well documented in ADC documents btw!) and resumed, as if you had never closed it. This is why Android OS & other have so many problems with lagging and freezing, memory leaks etc - they want to keep as much running as possible,
even when the user has no possible way of using that background task that is sucking up cpu cycles and hogging valuable ram.
Apple have nailed it guys, to be honest, and it speaks for itself with the sheer fluidity & stability of iPhone OS.
