What makes me surprise most is that the new iPod nano has a multi-touch screen. The 2010 iPod Nano is smaller and squarer than ever. Apple took off the click wheel and made it touch-based. Like the Touch, it now has an accelerometer and runs the new mobile operating system. You can watch videos and movies on it.
