I do agree with you that it seems a shame to buy something that's meant to be of "exceptional building quality", and then cover it with a case because it's is highly scratchable.
People do like to get cases to customize their phones tho. That said, I know only of iPhone and maybe one or two others that "need" cases for their phones. Very few Blackberry users get cases, nor Android S3 people.
I am seriously considering an iPhone. Was thinking of the 5 in black, as it's more "immersive" than White. Tho white I hear is much less prone to scratches, or fingerprints on the back.
My gf has a 4S with a case and she loves it. But isn't it better to "upgrade" if the option is there?
I wonder if there is a way on this forum to ask: Go for Black or White - and your reason. Tho I think there are more than enough forums and threads out there with answers to this.
But YES... I agree. Seems a shame tho when the 5 is faster, and better in (as you say) many ways.
