Phone cases used to be about protecting the phone and looking good. Now it seems that smart cases are going to be the thing in 2013. You will soon be looking into the spec of the case as much as the spec of the phone.
It seems that iPhone cases are leading the way at the moment with these two cases.
Popslate offers a second e-ink screen for your iPhone and shown at CES in Las Vegas was the new Sensus touch sensitive case. Both cases are expected to be available this summer.
Which one would you prefer? I am looking forward to the hybrid of the two.
