with extra money = buy
without extra money = dont buy if you need money for something else

you can sell your old iphone... waiting is painful, nobody understand more than yourself since your brain trigger you to consider already

seriously dont expect much better in term of performance (like much better processor or RAM in next generation)

looking at the past iphone, new number = new design (les hardware improvement), with S = better hardware like processor double up etc...

Apple very clever in doing business... they introduce dual core in 4S, touch ID is 5S, 3D touch is 6S... 7? what to expect other than new design? if you do some research, you will notice those with S get a huge processor boost

you can see the processor benchmark here https://browser.primatelabs.com/ios-benchmarks although it is just a reference
