Is it worth upgrading from my iphone 4s to the new iphone 5s?

Is it worth upgrading from my iphone 4s to the new iphone 5s?

Personally I'd say no. IPhone 5s doesn't have a load of new features, wait for iPhone 6. They already released a trailer and it looks like it has a ton of new features.

Definitely.

bigger display
thinner
lighter
Touch ID
more RAM
faster data speeds
improved camera (with slow-mo mode & True Tone LED)
better front facing camera
iOS updates longer into the future
1st & only 64-bit processor for a smartphone
better graphics
bigger battery
louder speakers

Yes, that is a huge jump. This comparison shows the jump in specifications from the iPhone 4s to the iPhone 5s
