It's not the scratching. It's the lint and dust that are the problem.
I used the clear bumper (above) for my iPhone 4 for two years and while it was great to see the aluminum through the bumper, every two months I'd start to see the lint and dust collecting under the acrylic, had to clean it out.
Every hard clear plastic case I've ever had has scratched all to hell in extremely short order and I baby my phones (and cases) to a ridiculous degree. Never near keys or coins, carried in their own pocket in my purse, etc. Scratches are inevitable.
I have the incipio feather (i think... picked it up at target or walmart a yr ago). It's smoke on a white phone and I can see the scratches when i turn it towards a light... other than that it doesn't bother me in the slightest.
I used to have one provided by Apple for my IP4 and it got scratch quickly just after a week, making the phone look ugly. Gave it up and used a dark soft clear case instead and very happy with it over the last 2 years
Thanks for your help
Nope, I don't want a case for a case. But, since there are so many cases to choose from, I would rather pick one that will look nicer, as opposed to one that will look crappy quickly.
I had an SGP case for my 4S that had a clear back and silver sides. The back is still unscratched, but the plastic clips that hold the sides on broke. I had the case for almost a year before they broke though. No scratches on the plastic back.
