Apple has posted several new iPad TV ads featuring and comparing the iPad with the iPad mini.
Interestingly, the ads seem to focus less on comparing the devices and more on showing them working together. One would think the iPad Mini or iPad would be shown by itself to emphasize what it does best.
The image of one hand holding the iPad Mini conveys an important aspect of the device, its compact size and utility.
