I have a 4 with a 32gb right now and I only have like 200 pictures on it and about 4 music cd's... so... even with a small bunch of apps.... I have 28gb FREE! Do you think the newer apps will take a lot more space... or might the video be so great that I would use it enough... or.... is there really any reason to bump to the 64? My guess is NO... but, maybe for resale or whatever, I should. It's only $100, but I could use that for my future iPad3... whenever that appears! PS.... sold my 4 in less than an hour on eBay for $350! I'm happy with that!
