My pondering is this, with the ipad mini living on and the ipad 2 doing like wise both with a geek bench of under 500, these are the products that ios8 will be built to run adequelty on. The fact that the retina models have geekbench scores of over 2500 is largely redundant (sure it will be quicker but let's face it the mini and 2 are still plenty fastf or most tasks). Now couple that with the fact that the air and retina will once the next model is out stop getting full features despite the fact they could run probably ios 14, does this not make the retinas non future proof? The trend is that full features stop once the device has been replaced by a new model. So with that being the case and ios and apps being built to run on much less powerful hardware, what justifies payingf or something 5 times more powerful when the reality is the user is unlikely to get the full benefit of it? Not being critical, this is something I am reflecting on as I consider replacing my ipad 3 with an air. Please don't reply with because its lighter!!
