I have an iPhone 5, and I love it. I use it everyday. If my main uses are web browsing, texting and email, is there any benefit to me at all in getting a 5s? I do want the best that is available, but if I'm not going to see much of a difference in a 5s from a 5 with the activities I listed, I'll just stick with my 5. I'm not a gamer at all, and I don't intend on taking advantage of the M7 or the 64 bit in regards to gaming. Is the speed difference that noticeable? Thanks!
