On the outside, changes to the iPad 3 may be minimal, suggests iLounge. Site editor Jeremy Horwitz says that yesterday he was shown an alleged prototype of the new tablet at the ongoing Consumer Electronics Show in Las Vegas. The hardware is described as "roughly 1mm" thicker than the iPad 2, which Horwitz adds that he's heard will cause no problems for accessories except those precisely tailored to the iPad 2's back. Buttons, switches and ports are otherwise said to be identical.
