How long has it been since you last used ios? Do you own an iPad?
I had an iPad about 4-5 months ago and I have an imac and macbook air. Ios I've dabbled with on my wife's iPhone and i don't mind it at all.
Selling the opo has nothing to do against the device or os as I love both but always said I'd try iPhone again if they gave us a bigger device. They have, I am.
