I honestly don't know why samsung releases new models every 7 months.
But, S4 should have better features
You dont know ? come on haha MONEY!!!!
If you can only afford a S3 get an S3, there really is not that much difference apart from slightly faster
processor and more mega pixel camera, oh and a useless thing called airwave or something.
Also have a look at the HTC One, a magnificent looking phone.
I think that is the main selling point with mobiles, to show offI know it's to make money.
My friend recently bought a S3 and he was like on the top of the world. Pretty soon the new model (S4) came in and his was extinct.
When they start releasing new products immediately, they lose the momentum of their customers. Now the mindset of most of my friends is like "They're gonna release a new model soon so why bother?".
Of course, if you're loaded with bucks then it won't be a problem
