One of the big talking points regarding the recent PS4 rumors is, of course, the infamous touch pad controller.
It’s worth noting that, despite some of the initial fan outrage suggesting that Sony is copying Nintendo once again, there’s actually a difference between a touch pad and a touch screen – and some fan-made mock-ups do an excellent idea of demonstrating that difference. The idea is something more like a laptop’s touch pad mouse – indeed, I made a direct comparison to Vita’s rear touch pads – than Wii U’s stylus-y touch screen.

Again, these are fan-made, not actual official concept images.
