Our Italian friends from Setteb.it reports a problem with a new iMac: dust accumulated in the space between the glossy glass plate and the LCD panel. Of course one can remove the dust by disassembling the plate, but it is far from being easy and can not be performed by all customers. The dust had a texture similar to metal dust. They think that the dust could have been stored in the iMac and was then further distributed when the computer was turned on.
