What's the difference between iphone 5s and iphone 6?

Besides the size, how clear pics look or how fast it is. What's the wow factor of iphone 6? If i want to spend $900 i want it to be more worth it that my ipad 2

What do you think?

If all you are going to do is play games, browse the Internet, text messaging, and similar tasks then spend $900 on a good chair and computer, skipping the IPhone 6. It's slimmer, the 6s is bigger, and takes better pictures. I haven't seen anything else that "wows" me about this phone, especially if you have an iPad 2.
