Easy to use and looks good.
You can do almost anything on the 4s, from taking pictures to surfing the net. It's quick and very sleek in its design both tech wise and looks. App's are in there thousands and there is pretty much an app for anything. Personally I feel the iPhone 5 is no better than the 4s. Apple pretty much got it right with this one and the 5 was just not enough. Let's face it though, all other phone companies are just following these guys!

Siri is brilliant! taking a memo couldn't be easier or sending a text. Speaking of text, this has to be the easiest phone I have ever used for texting, being touch screen you would think it would be difficult but it pretty easy. Enough space for even the big fingered people of the world.......

The 8MP Camera is brilliant, good auto focus. The flash can be a bit of a pain when using a cover on the phone as the light seems to be almost to bright for the space of some of the covers so investing in a good cover made properly for the phone is a big yes!!! But overall a good camera which can be used instead of bringing your normal digital camera.

I don't feel another phone could beat this one but that's just my view.
