I may return to Apple
I used to have a 4S but when it came to renewal, apple did not have the phone I wanted (i.e. a bigger screen) so I did what many did. I went with the HTC one.
However I've never really got on with Android, I find the whole interface and usability just a bit messy.
I do however have another year to go on my contract. I'll install IOs 8 and my ipad and see how it goes. 5.5" is however too big for my liking. Pity the 4.7 does not have the optical image stabilization.
