The Blackberry Storm Screen Takes on a Knife

Yes, my friends, the Blackberry Storm screen may be the hardest material on Earth.

I enjoyed watching some guy take his pocket knife to the Blackberry Storm screen with nary a scratch, but things only get better as our host frantically searches around the room for a sharp enough implement to upstage his first trick. [via Engadget]

iPod touch Passes Gentle Scratch Test

Look out, iPod touch! There comes a scratch test with a safety pin, a car key and then even a razor blade. But this tester doesn't seem too hell-bent on damaging his precious touch. Would a jackhammer scratch it? How about a blowtorch? We could run over it for you, guy—that might help. But still, this touch is a lot tougher than that first iPod nano we got, looking like a skating rink after about six hours. [YouTube]

iPhone Stress Test: Scratching and Dropping

PCWorld is sadistic. To simulate a couple months of usage (read: damage), they threw an iPhone into a plastic bag with a set of keys and jiggled it around like crazy. They then rubbed the two together next to a table, to simulate when you'd go and rub your crotch next to a table—what, you don't do that?

In addition, they went and dropped the phone on carpet, tile and the concrete. The iPhone pulled through with barely any scratches thanks to the keys and just a little bit of scuffing on metal edges thanks to the concrete.

We cringed at all the tests, but this should give you a semi-accurate view of how the iPhone does after a couple months abuse.
