It's not bad to have an option to extend the storage.With iPhone, Apple gives an option to decide how much storage user wants. That's why they ship 64 GB model from day 1. And even with 16 GB model, they provide users 77% free storage with lesser bloat.Although I would say iPhone has been stuck on 64 GB for a while now. This year Apple increased iPad to 128 GB. This fall I wouldn't be surprised if they up the ante with iPhone as well. And I would gladly buy the 128 GB 5S.
