2013 is gearing up to be the year that Apple releases new designs of it's key products iLounge reports. According to their "most reliable" source, they say that the iPad 3 will be slightly thicker (.7mm) in order to accommodate a possible Retina with it's twin light system.
The iPhone 5 will be released in the second half of the year and will upgrade to a 4" screen with an aluminium back.
As we've reported before, it looks like the MacBook Pro line will get a long overdue refresh to be more Macbook Air like and also probably lose their Optical Media Drives.
