I want to know the answer to the following question:
What other device shares the interface used by the iPod Touch?
All the background I'm provided with is that "All iPods (except the 3rd-generation iPod Shuffle, the 6th & 7th generation iPod Nano, and iPod Touch) have five buttons and the later generations have the buttons integrated into the click wheel – an innovation that gives an uncluttered, minimalist interface.". Is that enough to answer the question?
Answer: no
