So I can keep my iPad 1 (16 GB WiFi) which is in great condition. Or replace it with my dads old iPad 2 (16 GB Verizon) that has a cracked screen. The iPad 2 still works, but it looks like this. For my uses, either one is fine with me. I'm just thinking down the road for resale value, which would be best to keep. Which one is worth more? The older generation in great condition or the 3G iPad 2 with a cracked screen? And how much would the screen cost to replace? Thank you.
