I've only had iPhones and have always had the 16GB version with no real issues. I usually am just under max storage, but am wondering if I should go for the 16 or the 32 with the S4. So, I'm wondering how my usage/storage needs may change with Android and if the SD card will provide the extra storage I need, if I just stick with the 16GB model. Any advice on this? Anything I should consider I may not be aware of? I understand there are some things that cannot be stored on the SD card? Help appreciated.
