I have got a a 4G 64GB iPod Touch and have managed to crack the screen for the 2nd time in a year. Going to keep case on in future. Options are: 1. Repair Screen at cost of 90 2. Take it to Apple for replacement at cost of 190 3. Buy a new 5G 32GB for about 230 (now I have an iPad, I don't need so much storage). Which would be best?
