Well considering I have had the 16GB for a year now (3G) and I only have 4GB left, I am getting the 32GB. What we don't know (maybe we do but I don't) is how much storage every minute of video consumes... I know on my HD flip i get about 2 hours of video for 8GB of space...
That's an interesting point also for me .. Anybody out there who can already estimated what a minute of VGA video probably will take?
