hi all,i have an ipad mini 4, and i really like it for reading kindle books etc. for my iphone, at present, i use an iphone 6 and have gotten used to the overall size of this device. i am however, next month, upgrading to an iphone 7 here in the uk. do totally blind people recommend the 7, or the plus? i thought a plus, was only more useful to those with residual vision? is the 7 just as good as the plus, for an individual with no sight, like me, and is it the same size as the 6? thanks to all Will.
