What is the difference between 16 gb and 32 gb on an Iphone 5?

So I'm going to get an Iphone 5 from t-mobile as a pre-paid and I checked out the prices and it was $650 for a 16gb and $750 for a 32gb. So what are the differences bettween 16 and 32gb and is it worth paying $100 more for double the memory?

32g is way bigger and faster and it can take more medias than the 16

32 gb holds more music and movies and stuff like that I have the 32 hb iPhone 4S and I have 7 movies 600 songs 700 pics and like 40 apps so I would say yes it is worth the extra $100 if you want to have alot of stuff on your phone

Well it depends if you think 16gb Will be enough, if you think you might need the extra storage then you might want to spend the extra $100 to get the 32gb

The difference: 16GB.

That's it. If you feel you need the extra space then by all means. If not, then the 16GB.

@Hamooudi: both models have the same speed.
