Apple has two products that are just asking to be merged into one device...which is the MacBook Air and the recently released iPad. A little digging uncovered a patent drawing from the Cupertino company that shows a device that may be just that! The drawing from Patently Apple illustrates a laptop that has a monitor that slides in place to create a tablet device... Also to add, in recent news there has been rumors about Apple redesigning the MacBook Air... I guess time will tell.
Below is a Photoshopped drawing on core77 showing what it may look like...enjoy!
