Should i get the 32 g or the 64 g iphone 5s?

So i've been saving up for a long time for this and when it finally came out i was ready to get it, but should i get 32 g or 64 g? I already have a 64 g ipod touch and its about half full so the 32 g should get me by but should i get the 64 g? I have the extra money but i could get some accessories if i got the 32 g.anyways i'm planning to keep it for about 2-3 years so what do you think?

If you are sure that you will keep it for 3 years then I say you should go for the 64gb version cause you can accumlate a lot of data in that time, but if it is anything less than 3 years its not worth the money even if you have the spare cash lying around, like you said its best to buy some accessories with that extra money that you have.
