I personally grew up with a Purple iPod Nano 4th Gen, my dad had a Blue one (still have this!) and a 4th gen shuffle. I'd have to say that the current iPod I have now (6th Gen Classic 80GB) is probably my favourite. The larger size of the device makes it so much more comfortable to hold compared to the nano line. Unfortunately, my device has got a Black Spot™ growing, and the 6th/7th are a pain to open, so that's annoying.
