iLounge is today reporting that the next-generation iPod nano will feature a taller design. According to the iPod news and rumour site the screen will match the aspect ration of the iPhone and iPod touch which is 1.5:1 up from the current 1.33:1 found on the current nano.

To fit the screen and Click Wheel neatly together, the new nano will adopt a form factor that shifts away from the almost square dimensions of the 2007 third-generation nano back towards the general shape of the first- and second-generation models. As one of our sources noted, it’s a surprise that the new nano will be bigger than the prior model, but the goal appears to be preservation of all of the prior model’s usability while adding a bigger screen, and there aren’t many other ways to accomplish that goal.

The article also notes that a recent rumour by 9to5Mac that the iPod nanos will be multi-coloured is “most likely inaccurate”.
