Quick question: I currently have the new iPad 16gb wifi version. The storage space is making things tight; between games, apps, and books I do a lot of juggling. I want to use some guitar apps that would take even more space up. So help talk common sense to me. Is it worth paying an extra $170, to get the 32gb size one? I am selling my 16gb for about $430 on craigslist, and then buying the 32gb for $599. Is doubling my storage size worth it, or should I continue to juggle and save the money for something else? I know this is s personal preference/decision, but has anyone done a similar upgrade and found it either worth it or not? Any other advice? Thanks.
