The above trickery could have been written by Microsoft. The SP3 with the keyboard weighs more than the 13" MBA, how does weighing more equate to 'much lighter'? EDIT: my bad, some confusion with gms and lbs, 235gms lighter.
I would not be surprised if the entire iPod like iPhone leak is one of the greatest hoaxes ever successfully pulled off by Apple and instead they release the iPhone 6 that is nothing whatsoever like the leaks, and has a radical new design like wall to wall curved sapphire.
FOOLS! These crystals are the key component in a new technology designed to communicate with alien civilisations who are already taking over the planet. Look at the new 'flying saucer' Apple campus. We are all doomed.
