Is there really that big of a difference between the iPhone 4S and iPhone 5?

It doesn't seem like it is. Is it really worth paying more for the iPhone 5 rather than the iPhone 4S?

What's the differences between them? I mean, is it even worth upgrading from iPhone 4S to iPhone 5?

The only difference is the 5 is bigger and lighter. All the hardware is the same though. The 5 is not worth the extra money. Just wait till they come out with 5s or whatever they decide to call their next tweak to the current iPhone.

There's very little difference between the iPhone 4 and iPhone 4S except for seri and a new camera. The Iphone 5 comes with a better processor supposedly stronger glass, and a new liquid metal casing.

I don't see the point of an upgrade if your just going to use your phone to play angry birds but it's up to you.

Hardware is far better in 5. Anyone that says differently simply has no idea what they are talking about.

IPhone 5 - Review from an owner of both (4s and 5):

There are not many differences, Its just that they upgraded the inner hardware. Like the new chipset to reduce battery usage and increase performance. All mentioned in the Review I just shared with you.

The screen size obviously does matter a lot. Then RAM being 1Gb makes a difference in multi-tasking and running some apps easily. Then the front facing camera can now record up to 720p. So I would recommend iPhone 5.
