it has been a while since i got any sort of new gadget, (my current ipod is over 5 years old) But i cant decide whether ill actually benefit that much from having a new ipod touch 4G over getting someones used 3G. i do think the cameras are a great addition, but the quality makes me wonder if its worth it since i keep reading that it is only .7 megapixels for the still cam. i realize MP arent everything but i cannot help but think about the fact that my basic motorola flip phone has a 1.3MP camera... Also im reading that the 4G still only has 256mb ram.. another reason the 3G may be just fine. Convince me all the other upgrades are worth it or that the 3G would be sweet enough. Also wondering if people have an idea of how their hard drive space is used. id go for a 32GB model and would like to have about 15-20GB for music, would the remaining 10-15 gb be enough for a bunch of apps as well as some pics&video?
