I'd been undecided between the 32 and the 64 until i got on line around 3pm on launch day. The argument in favor of the 32 was I have never used more than 10 on my 16GB iPhone 4. The argument for the 64GB was that I never put any video on my iPhone 4 either. I could probably get by with 32 just fine even with adding video to the mix but maybe not and you cant add memory down the road. I also figured the 64 might be less popular than the 32 and that going with the more expensive model would increase my chances. I ended up with the 64 as planned, 56.3 GB of 59.1GB still available. No video yet but I really think I would have been just fine with the 32.
