Retailer Apple Magic Trackpad

Product Name: Retailer Apple Magic Trackpad
The latest Apple Magic Trackpad (the one with the more rounded corners and the woven cable) some people are calling it the 3 but from what I understand it's not really a new model just slightly updated from the 2? Honestly I'm not quite sure exactly what the difference between the two are so I included a picture of this one next to my older version 2 for reference. Iv only used it once to test it out but I already have one that works fine and don't need two! Let me know if you retailer have any questions!.
