Had my 6 Plus since February, and after a slump of me being bored of it, I realised it performs a lot better in games etc than my Android phones have done in the past - this includes a Nexus 6 - and it doesn't appear to be slowing down either. I was a bit miffed by it the other day when I took it out of my dual layer case (thinking it was receiving adequate protection) and noticed it was bent by the volume keys. After bending it back myself, getting the screen replaced and now having a supposedly more structurally sound case in order I'm pretty happy with it. With the 6S coming out, I'm not sure if I should, or shouldn't upgrade. I could sell my 6 Plus for a decent amount I reckon, maybe £400ish (?) add the rest and get a 6 Plus S, but I'm not sure the upgrade is worth it. Other the possible 2GB RAM - which would help in Safari, is there going to be a vast difference in performance? Besides a slightly faster CPU, stronger aluminium (that would've been nice last week), upgraded camera, Force Touch (how useful is that gonna be?) I can't see how much of an upgrade the 6S will be compared to the 6. And if I'm right, the 6/6 Plus are going to get full versions of iOS 9, so if that's the case I can hold out till the 7... unless I'm missing something and am going to regret not going to the 6S. Either way I could use some opinions.
