My iPod is so damn old (and at 4g no less) that I need an iPod stat so I can use it while I start jogging. Should I get: 1) iPod Nano with touch screen and a clip so I can run without holding it in my hand? 2) iPod Touch so I can double as a gaming console (Angry Birds FTW) from time to time? 3) iPod Classics with the largest memory of all 3 options? Thanks for any help.
