We've heard about this before
, but a new patent illustration hints again
at a second dock in a future version of the iPad, one that will enable you to both charge and sync your iPad from a landscape setup. Honestly, it seems a little redundant to have two dock connectors on there, since you'll never use more than one at a time anyway.
Still, competitors are already making use of a landscape charging setup
, and Apple's been hinting about switching to a landscape charging display
for a while. Could be that when we do see the next version of the iPad announced (likely next January), you'll have your option of which way to display it while charging.
