The obvious reason for more RAM is so that the phone has to spend less energy getting costly resources over a 3G data connection again. It is important to note that all desktop operating systems are different from their mobile counterparts in that desktops can stick data in RAM onto the hard disk to be used later. Sure, there's a penalty when you have to grab that data from the hard disk again instead of RAM, but it's MUCH better than having to access network resources (and on a mobile device, using 3G is the largest penalty there is).
As far as I know, none of the mobile operating systems have virtual memory because they don't want to wear out their Flash chips with continuous read/write cycles. Desktops and laptops don't really have this problem. Even Windows 8 tablets will write data to virtual memory.
So I don't really buy the "less RAM = more power savings" argument on a mobile device. Any savings gained from having less RAM would quickly be wiped out by having to re-download images and other media assets from the web.
Yes because you know more about this subject than the ENGINEERS at 2 of the biggest companies in the world....
I have always said this to my cousin who seems to love the phone with the best specs. I would just say "wats the point of having these 'SUPER GREAT SPECS' if your really not going to use them all that much on the phone, its more efficient to put in the specs NEEDED to perform the tasks that it can"....my point is that all these android fans love their specced out phones but is it really worth it to having a shitload of memory if your batter life is going to be shit? Apple knows how to make use of what they have and somehow still beat out the competiton with better specs, and then to put the their foot a little further up Android's ass they have way better battery life.
