So my iPod 4th gen is starting to not work anymore. Its never held a charge long but now its battery life is even shorter. The voice control will randomly come up on the screen without me doing anything. And now I will be listening to music and then the sound disappears along with the play, pause, and volume buttons but then it shows the song still playing. Now that I have some cash I'd like to replace the iPod 4th gen and I was looking at the 5th gen or the iPod mini. I like the iPod because of its small size allowing me to take it everywhere with me but with the iPad Its easier to play games with the larger screen. Is there much of a size difference? Or will there be a even better 6th gen iPod out soon that I should wait for?
