HI guys, I have just got the new S4 but now that the new iPhone is coming out I think I may have made a mistake. The S4 does lots of things brilliantly but I have a Mac and ipad etc at home and the new iPhone is a week away. Should I return it and get a 5S? It is hard to know since the phone isn't even out yet and will cost an extra £150 up from I am guessing. What should I do?
