Apple has never raised prices on capacity bumps before; I'm not sure why this would be any different. By your logic, there should even be a 32GB option. I'm one of then people who wants at least 128GB; if I'm truly using the phone as my iPod, phone, Internet, and mail, why shouldnt I be able to carry all my media on it. Hell, that just music, I could top out a TB , but that's a ways away. As far as puttin everything in the cloud, seems like pretty bad idea. Data caps and battery drain are the obvious ones, but let's say I want to listen to music on the train, or plane, or when I'm spelunking? It doesn't make sense to be reliant on an Internet connection to access your media.
So that works for you, buy a lower capacity phone. How is having more space a bad thing? I guess you're right though, it's not like you can buy movies directly on your phone, shoot hd video or download apps that are hundreds of MB. Because if I had a phone like that which I was using on vacations and trips I'd want as much space as possible. Also, why don't you put most of your books and movies in storage? You're never going to read or watch all of them at once. Oh what? It's actually inconvient t because you don't know if you may randomly feel like watching one of your movies during the day and it's inconvenient to drive to the storage unit and grab the movie and then drive back? Or I guess we could store everything on external hard drives, we don't need to be able to access all of our files at the same time, right?
