Canadian iPad buyers have been distraught to open their boxes and find a tablet of clay. It seems unscrupulous individuals have been buying genuine iPads and refilling the boxes with heavy clay. After shrink-wrapping, the clay-filled boxes are then ready for refund at the unsuspecting store. Some buyers have even found clay replacements for the power supply unit nestling alongside the the dumb iClay. I suppose it could have been worse. The crooks could have replaced the iPads with BlackBerry PlayBooks.
