A newly secured patent by Apple indicates the firm may be looking to update its MacBook range with a second touch panel.
Wording of the patent suggest that Apple may be looking to incorporate a touch screen to the lid of the MacBook, which work function much like an iPad or any other tablet.
In particular, the patent describes "A system including a capacitive array element capable of sensing touch from either side is described."
More interestingly, however, is the portion of the filing that states: "The track pad device may include a display element and the capacitive array element may be translucent."
That would suggest a MacBook device which sports a traditional keyboard, however, a touch screen that is functional when the lid of the device is closed.
