Music makes sense, much smaller files than the 16GB increment....I don't listen to music. I could have all of my spreadsheets and some scanned docs on it and still only take 6GB...I would have no idea what to do with the rest, maybe fill it up with podcasts, still, cannot consume fast enough.
This ugly train of cables essentially killed the need for carrying my laptop for traveling....All I need is the phone and a drive to move data.
What I had in mind is what killer app is enabled by 4G that I am unaware of and if those killer apps take up storage. Then it would make perfect sense for 32GB.
