I went to the Apple store today, and on the display models, when you press the home button, the screen does a dissolve to the home screen. Which is unlike the iPhone, which does the screen zoom transition when you press the home button. On the Touch that I own, it does the screen zoom as well when you push the home key. I wonder why there is a difference between my iPod and the ones at the store? Anyone else's Touch do either the Zoom or Dissolve transition only?
