I kinda like the rubber/plastic feel to be honest, and know I'll be very much alone in that! Makes it far less likely to slide out of my hands and get itself a nice big dent in the bezel or shattered back/front.
I've got the Zagg invisible shield (front/back/sides) and despite what some other people have said, I quite like it. Good trade off between a bumper (good grip) and no case (looks better).
Takes a little time and patience to fit it (and a couple of days for the bubbles to vanish), but I'm very happy with it.
