This morning The Times newspaper reported problems with the iPod nano.

It reveals that UK high-street electrical retailer Dixons is selling five iPod nanos every minute, but warns that some new owners are complaining that the device's screen is easily scratched.

Staff at Apple's Regent Street store are receiving multiple such complaints.

A US website called FlawedMusicPlayer.com has launched, and is gathering stories of iPod nano woes - mainly claims of "inexplicably cracked screens".

Apple says its designers created the screen using the toughest polycarbonate available.

A review on Ars Technica describes early stress tests on the product.

The site found the device extremely resistant to damage - the music still played even after the player was run over by a car, although the screen no longer functioned.
