Is the iPhone 5 64GB necessary?

Would the iPhone 5 16GB be good enough or is the 34GB or the 64GB really necessary?

I currently own the HTC Evo V 4G from Virgin Mobile and I want to make the switch to iPhone from Android.

Added (1). I love taking pictures, but that's it.

The memory is mostly to store videos or pictures, so if you don't do that, get the one with less memory.

Depends are you going to be downloading movies and tons of music?

We need more detail like do you use loads of apps and take alot of selfies and have loads of music if so then yeah but if your unsure just get a 32GB.

32 gb is enough, but 64 gb is way too much storage space, unless you like to download A LOT of apps and music.

Better to have too much space than too little.

It depends on what you are doing. It's easy to run out of space. I always buy as much as I can afford.

Sixteen gigabytes will hold about 4000 photos, or 4000 songs, or more than 600-average sized apps, or about an hour of high-definition video.
