8GB was enough for me the last time around, but does anyone think that the availability of the App Store (and all the apps/games I will be downloading) will take up enough space to warrant an upgrade to the 16GB?
with the potential for app's to take up to 2GB of space the 16 Gb is the way to go.
Well the only reason I am upgrading is better audio, and I am sure that apple made some other changes. They just don't know us to know that.
