How desperate has this change in fact been over the years?

It's been over four years back the aboriginal iPhone came out, and a lot has changed, from the awning to the CPU to the anatomy factor. How desperate has this change in fact been over the years? Not fast enough.

(Each band of the blueprint represents a altered iPhone blueprint that applies to every generation. Anniversary mark forth the x-axis represents a new iPhone model. Every consecutive access or abatement doesn't accord to the raw numbers of anniversary spec, but the agency by which it increased. Every blueprint in the aboriginal iPhone starts as a baseline value, appropriately the flatline to start.)

It's not like the iPhone hasn't improved. Statistically speaking, the camera, accumulator and the RAM accept accomplished the a lot of desperate changes over the 5 ancestors of iPhone, with the camera getting bigger every bearing afterwards the iPhone 3G. The CPU has aswell apparent abiding advance afterwards the absolution of the 3G, admitting not at the aforementioned clip (in comparing the A4 and A5, I acclimated the prevailing argumentation that a dual-core processor is ~1.6x faster than a single-core CPU of the aforementioned speed).

But why doesn't the iPhone accept a gig of RAM like the Galaxy S II? Where's the bigger, bezel-less screen? Granted, they've been abandoned by manufacturers as far as accumulator accommodation goes. But as the better and a lot of avant-garde aggregation on the planet, there's no acumen why they shouldn't be aggravating to not alone beat Samsung, but aswell themselves.
