A report from warranty provider found that one in 10 owners of the iPad 2 had reported accidental damage causing a problem with their device within 12 months of purchase, compared to just 2.8 percent of owners of the original iPad.

SquareTrade's report says that differences in the design between the original iPad and the iPad 2 were responsible for the differing level of malfunctions. "In addition to being thinner, the iPad 2 glass is exposed slightly above the bevel, as opposed to the iPad 1, which has glass that is more protected by the aluminum frame at the corners.

"Compounding the issue is the curved shape of the edge, which increases the likelihood of impact occurring on the leading edge."

The report also states that anecdotal evidence suggests that the iPad 2's Smart Cover could have something to do with the increase in accidental damage. "The iPad 2 smart cover may be contributing to breakage rates based upon improper use by the consumer of the cover as a means to "grab" the iPad.

"Customers have reported using the Smart Cover to grab a falling device, only to have the cover - not intended as a fail-safe protector - come off the iPad 2."
