What device should i take on holiday?

I'm travelling overseas in 5 months and I'm thinking about getting a device to take with me, but I need some help deciding…

Now two things the device needs:
1) The device needs to have a decent camera.
2) The device will have enough storage for lots of photo's.

There are two devices, I'm interested in… One is released the other has not been released yet. I will explain my dilemma so you can understand why i'm asking this.
1) Released: Samsung Galaxy S4 ; Full-fills my needs and the pictures look great, however i won't feel very secure cause of android. Also device connectivity (meaning being able to transfer things and manage photos) could be a pain as i have a mac and lots of songs in iTunes.
2) Not Yet Released: "iPhone 5S" or "iPhone 6" I know it will Full-fill my needs, based on leaked information on rumour sites. However I know for a fact that Apple's camera solutions are always fuzzy and you can never get a good picture, but I will feel secure and have a good time with device connectivity(meaning being able to transfer things and manage photos) as i have a mac and lots of songs in iTunes.

So please let me know your thoughts on which device i should get, Thanks!

PS: I may just end up getting a camera, but the downside. I won't have Whatsapp!

That seems very circle. First make sure what your priority is about. Means you want to emphasize on taking photos or just hanging on WhatsApps & all that? I recommend you to take Galaxy. How many days have you left to departure? If you have time enough to transfer your favourite playlist, do it on Galaxy!
Ain't it possible to take Galaxy s4, mac & camera along? If you leave camera at home, you left everything.
