Shame it's not a 5 but it wont stop me joining the apple revolution

I got an ipad earlier in the yr and it's gone down a storm. I HATED the thought of apple before.

I can hopefully get a 4s ordered and waiting for me when I get home on the 27th

So what memory do I need?! My ipad is 32 gig and I cant see I need much more. How big are photo files on the current phone?
