I have the iPhone 8 Plus 256GB and I'm fine with it for now.
If the 11's camera SMOKES the 8 Plus - or if the iPhone 11 Pro camera is even better then I might jump. the night mode Google has is good - if iPhone can beat that then it's a maybe.
I will be getting the iPhone Series 5 because of the S5 processor - the watch needs to be faster - the S4 was close to fast enough, the S5 should be good.
(I'll sell my Series 4 for 250-320 - whatever I can get for it.)
