I have the OS taking up space, games that now take up 1+ GB, some offline music, and offline maps so I can use the GPS in rural areas. All of that eats up a sizable portion of that 32 GB. Add in photos and 1080p video and it doesn't take long to fill up. If 32 GB works great for you, awesome. But I didn't make my story up :-)

Now my phone has 64 GB based storage and I'm still in the same situation because everything has bloated to fill the available space. microSD is a really cheap and incredibly effective solution to the problem. Certainly much cheaper than buying a new phone so you can get more storage.

Not doubting you at all. Also, I recently bought a 128GB iPad and copy my pictures to it - from phone and camera (using the SDCard adapter for iPad). It works great for me. iPads are cheaper and last quite a bit.

Maybe HD video is the major culprit. I imagine that might fill up space pretty quick on a vacation, depending on how someone likes to record.
